  1. Today
  2. Just wanted to stop in and wish everyone a happy 626 day. Give your car some love today.
  3. Important to remember that tire height plays a big role when swapping tire sizes. The acceleration performance difference between a larger diameter wheel with a lower aspect ratio tire and a smaller diameter wheel with a higher aspect ratio tire will be negligible. Much of what people see is because of a change in tire height and when the car is only making ~100 whp at most, the loss of gear is magnified. This is one reason that we probably won't run the 235 RS4. It's about a half-an-inch taller than the 225. We also think that 158 whp is going to need a little more tire. Note that we had the wrong weight for the Konigs because we thought it was a different wheel. Actual weight savings is ~1# per wheel, so not as good as we thought. And these are a forged wheel, so there should be no durability issues.
  4. Hmmmmm... interesting! Will definitely keep that in mind!
  5. Funny you should mention that. I have a set of Wilwood calipers, rotors, pads, and brackets left over. I was poking around the garage this past weekend and discovered the box. They came off the Probe. I'd be willing to swap them for payment for a seat on a race weekend. I could check them on the plane with me, so no crazy shipping costs :-) I agree that the Speed6 brakes are a little too much. But, I do think the standard 6 setup you have is reasonable.
  6. Hi all, I recently bought an unusual car here in NZ, a 1985 GLX 626 2.0l coupe. Have never seen another one at any stage and most people around here have never seen one either. My question is the paint, it's gold in colour with a greyish lower section that is heavily faded, but no where on the net can I find any reference to the Mazda paint code QS, plenty of gold codes, but all single digit. While the 626 sedan & hatch were assembled in NZ, I believe only a small handful of coupes were imported across all the years, making it a rare car here. Anyone out there have any ideas? Thanks, Tony
  7. Wider tire doesn't necessarily mean more grip. I can only speak for the Miata, though this 626 is now about the weight of mine. The consensus with the Miata is: 7in is 185, 8in is 205, 9in is 225. Those yield the fastest times. This is from the top Miata guys in NASA/SCCA/etc and I agree. I tried the 225 on 15x8 and 205 on 15x8. I'm sticking with the 205s.
  8. Yes, dont disagree with a theoretical maximum size. It could even be that 245 is somewhere near the limit for that power. As I mentioned, hopefully i can contribute some hard (and subjective data) to the topic after this coming weekend. I can also note that it sure seemed (by the butt dyno) that the 235/40/17 had more getup than the larger (by a significant margin actually) 235/45/17. First prize in my mind is finding a similar lightweight 15" wheel in a 9" (or 10 even) and go with a 245/40/15. At the same time find a set of wilwood calipers and pair them with a smaller (read lighter) rotor as I feel like our brakes (and your Speed6 even more so) are a bit of overkill. Ive challenged my teammates to find a lightweight 15" wheel and I will buy and make the upgrade! The only stuff we have been able to find so far though is in 4x100 bolt pattern Also, per a previous comment, the Mazda 6 (and subsequently Speed6) wont fit inside of a 15" wheel, but will fit in 16" or greater.
  9. Yesterday
  10. Yeah, bigger tires will last longer and more grip is good because those Speed6 front brakes with the DTC-60 compound are very grabby. In fact, I discovered the biggest threat to tire life is the combination of no ABS, high friction pads, and new drivers that are used to their BMW/Mini Cooper track cars with ABS brakes. It's not a dangerous combination, but my team did flat spot a number of tires until their ranks solidified and I had less turn over on the team. The extra power with that proper tune should be enough to step up to the 225's or even the 245's without issues. I was just pointing out that there is a theoretical maximum size for the best tire setup on a given car, and it's smaller than I would have thought (at least for the lower horsepower cars). Bigger isn't always faster.
  11. Correct, but we are endurance racing. So you might sacrifice some ultimate speed for some reliability and longevity . The wider tires will ultimately last longer whether we go to a 225 or 245. There's physically more rubber to heat up thus making it tougher to over heat and wear them down. The fact that we now get to offset the added weight of the wider tires with lighter wheels really helps the overall setup. Brake performance also improves with the wider tires as there's more rubber on the road to stop the car. Remember, brakes don't stop your car, your tires do. The car will also probably going faster than it has before with this motor. It will have the power to get the car out of the corners off the optimal line if required. I think we might get 3 races out of a set of RS4's on this car due to the weight if we went 245's. The 225's would go 2 races I believe, they might go more. This will bring down the overall running costs of the car while improving the performance. The 255's RS3's we have on our 300zx went through Road Atlanta and Daytona and still look pretty good honestly and that car is not slow. We were 11th overall at Rd. Atl when we retired due to trans and ended up 6th overall at Daytona. If our next race wasn't 24 hours we would think about leaving them on the car depending on the track we were going to. I know we will probably have have a lengthy discussion in regards to the 225 vs. 245 decision.
  12. Temps aren't a problem on 200tw performance tires. If anything, you have to worry about them being too hot. And lighter wheels are always better than heavier wheels, unless you are sacrificing durability. I doubt these new wheels are notably less durable than the Konigs. But, the diameter and width of a wheel/tire package is not so clear cut. Especially on lower power race cars. First, there is the final drive ratio. Bigger outer diameter tires mean a taller final drive ratio. It's noticeable. Second, there's the moment of inertia of the tire and wheel. A smaller diameter wheel/tire will have a lower moment of inertia than a larger diameter wheel/tire of the same weight. If the smaller diameter wheel/tire is lighter, then it's an even bigger difference. Also, losing a little weight in the tire makes a bigger difference in the moment of inertia than losing some weight in the wheel which is closer to the hub. Also, keep in mind that you have to consider the weight of the brake rotor too. All of this makes a noticeable difference in how the car accelerates. For instance, we originally ran 14" Direzzas on steel and then factory alloy wheels. When we decided to update to 17" wheels, we did a head to head comparison (different days a couple weeks apart) of the car on the same track. The car felt more stable on corner entry, faster at mid-turn, and noticeably slower acceleration at corner exit when we switched to the 17" wheels. But, lap times on an open track were the same for both setups. However on a busy racetrack, 17" wheel/tire package was a little slower on average. Since we had sacrificed corner exit and straightaway acceleration for corner speed, the impact of traffic on our lap times tended to be greater. If you couldn't run your optimal line at the optimal speed in any given corner, you lost more time. The 17" wheel/tire package made the car an even more "momentum" car. In the end we decided to stick with the 17" setup. Since the wheels had a much more open pattern than the factory alloys, brakes ran cooler. And when we took advantage of the extra space inside the wheels to install bigger rotors and brakes, they ran even cooler. Also, the tires ran cooler. So tires and brakes lasted noticeably longer. BTW, none of this was a surprise. A couple drivers on our team track their Mini Cooper S's on 15" wheels. It's a quicker more responsive setup than the factory 17" wheels. Also, I am running 15" Kosei K-1's with 225/50's on the Integra. They fit nicely over the Type-R brakes with Mini Cooper rotors so I can stick with the 4 bolt wheels.

  15. The 225 vs. 245 in the Hankooks is only a 1lbs difference. I believe the Direzzas in the 215 were 22lbs. The 225 RS4 is 24lbs and the 245 is 25lbs
  16. Yes, we got the ones from the chump forum. Cant' beat 6 wheels for that price. We hadn't planned on upgrading wheels but we'd be stupid if we didn't in this case. The wheels currently have 245 Direzzas on them. We will probably test with them on the car and see how we like that size before we purchase the RS4's we will ultimately race on. 225 vs. 245's it's hard to give up the extra rubber if you can fit it imo. We know we can heat them up.
  17. Last week
  18. RT @ahleeshaRanae: What's wrong with being married in our mid-late 20s? πŸ™ƒ if y'all love each other and know you not going anywhere, why the…

  19. I respectfully disagree with you guys! Inactive, did you buy the ones on the chump forum? Screaming deal, if I was closer I would have bought the whole lot of them and the tires! make sure you get some hub rings to fit them properly. They are pretty cheap and easy to find on amazon or other sites. As for the RPF1s, the 17x9 is only 17 lbs. the 8 inch will be even less. I would say it would definitely be a net weight loss in the end. There won't be any trouble getting heat into the tires (unless you guys drive really slow ). But the 245 may be a bit wide for an 8" tire, maybe? 225 should give a better feel (stiffer sidewall with it stretched to fit) but I think the extra rubber will be faster overall. We just did a test of our new 255s on a 9" wheel, but it's hard to say how it was as I wasn't driving, just some of my teammates were. Will hopefully have some hard data for you as we race next weekend. Mosport baby!
  20. RPF1s are awesome, they just dent easily on the street. Hopefully the tracks you run don't have potholes! If it were me, I'd stick with the narrower tire. I would think it'd be challenging to get enough heat into 245s with the weight of your car, plus running a 215 or 225 on the 8" wheel will stiffen up the sidewall. Save weight, save cost.
  21. Very cool. You'll get some of that weight back in bigger tires, but it will still be a net gain. With the previous tune/motors, the 215/45 R17's were more than enough rubber. In fact, I researched at one time swapping down to the standard Mazda 6 front brake setup and putting 15" wheels back on the car. That would have saved a lot of unsprung weight and improved the acceleration out of the corners noticeably. I decided to put it off until I ran through all my spare pads and rotors. Also, I don't remember if I determined a 15" wheel would fit over the standard Mazda 6 setup.
  22. I have a 626 that sat for a year tried to get it back on the rode and it will crank but no spark so I replaced the distributor and still no spark please help

  25. Hi all, I've just bought a 2001 626 Platinum Edition auto 2.0ltr. Like most people who join, "The car made me do it..!", for without it I would not be here. I Have been on Mitsubishi Forums, when I owned a 99 Verada and I am currently on Ford Forums as my other Car is a Ford Territory SUV. In joining I hope that I can offer as much as I can also ask in the way of help. No doubt, I will be needing guidance around areas of an unkown vehicle to me at times. The little bit we have driven so far, is impressive and after a year and a half of sitting up high in the Ford, I feel a bit vulnerable being so low on the ground :) About me, well... 30 years Military service, previously 5 years as a Locomotive trainee to qualified driver. Now medically discharged due to injuries and PTSD, other Psych condition army wont accept. On second marriage with a totally dedicated, supportive and understanding wife. Served as active intel gathering in Afghanistan from 2001 - 2006 Used to be passionate motorcycle rider, reader, and fly RC aircraft. Now, I have sold my bike, have boxes of books, some read and models still in boxes unmade and unflown. The one thing I still do and so far have not lost interest in is car maintenance and small mod work. Mostly appearance and cosmetic, or interior. It keeps me off the streets LOL :) Jeff
  26. We just picked up a set (actually 6) Enkei RPF1's in a 17" x 8". We'll pick up two more before the Sebring debut. They are ~6# lighter than the Konigs (each) and an inch wider as well as forged. So ~24# of un-sprung weight savings and we'll run either a 225/45 or a 245/40 tire. Things are coming together and we have some good stuff on the way! S.
  27. @BrendenG Is this political commentary or some kind of complicated political pun? I can't tell :-/
