Hmm. . . nice. Didn't know you could get a 245 wheel onto an 8" rim. I bought an 8.5" rim but the offset is only +45 and it sounds like I can't get even 225 on it lowered without some serious rolling. Might be time to put them on the market.[/b]
Yep, 245 is the widest you can/should go on a 8" diameter wheel. I should get a pics up...these tires are huge on the 6...
I'm curious why you opted for a much lower spring rate for the rear when you have such a high spring rate upfront..? Just testing it out? Although with all honesty, I don't feel the spring rates of D2/Ksports to be actually true - especially their rear rates. They seem a LOT less firm than the listed 9kg/mm...
In any case, you're saying it feels like how Mazda6sMtx is described his situation? I've driven his car, and I'm feeling that initial turn-in is actually quite firm, then mid-turn all of a sudden loosens up, then exit, it fights back and firm again... It's weird.. It's gotta be something with the alignment...[/b]
Sorry, should've mentioned my fronts are Megans with Koni's. Previously I had the fronts with the Megan springs and the rear with the KSport spring plus Koni's all around. I had the setup since the beginning of the season. When going left and right in the slalom the car felt unsteady. It could've been I was too abrupt with the turning but this was happening much more often than last season when I was running the Ksport all around. With the higher spring rates in the rear (whether it is 9 kg/mm or not, I can't verify but it was definitely stiffer than the megan's front), I was able to rotate my car more easily, a lot more easily.
Since I was getting an alignment, I decided to use the matching rear Megan springs and test it out. Now, the car feels more stable in the slalom and more predictable. Though I lost the ability to oversteer just as easily as I had before. But that might be a good thing for me. Even though before I can get the car to oversteer, I'm still far from able to control it once it breaks loose too quickly.
Yeah, the initial turn in is fine, but when turning more and more, it starts to just push. Again, it could be I was going too fast and the softer rear spring rate is causing it as well. This is only one autocross so I'll get a better feel next time out.
I've not run a competitive auto-x with my car but in playing around a bit on an Evolution school course during their lunch break I found one way to deal with the inherent tendency of the 6 to understeer was taking later apexes than I was previously used to. Mind you I come from a background of a V8 rear wheel drive F-body car that can oversteer by just thinking about it so my first couple runs ever with a front drive ATX car thru the cones took some serious adjustment in my driving style. A couple runs and some serious plowing thru a 180 sweeper made me consider the much later apex route and it did help considerably.
My car is pretty stock: 2006 6s ATX with only a rear RB bar and Bridgestone Potenza RE-01R 225-45x17's. I didnt even set pressures, they were still at the 35lbs I run normally on the street. I was 2 seconds slower than a fairly well setup STS Subaru STI on Falkens, so I wasn't too disappointed considering the circumstances.
I've got a set of Bilsteins in the garage, waiting for the Racing Beat springs to arrive and I'll change 'em all out at once. Mind you I'm not building any kind of a serious auto-x car, I think I've sort of lost my interest in it for a while, but just improving the handling of the 6 for my own personal satisfaction.
Just one man's opinions and experiences, your mileage and times may vary.[/b]
Yea, I was told the same thing. Because of the understeer nature of the car, brake until the very last moment, turn in, try to get straight as fast as possible, then power out. Our car isn't made to power through the turns.... Thanks for the advice.
