Track Setup Thoughts

What's everyone's thoughts on a non-staggered setup for the track. Dials out some of the understeer and allows for tire rotation...

I'm thinking 245 or 255's all around on 8 or 8.5" wheels.

Thoughs?

Thanks

I think there are going to be a lot of front wheels for sale on eBay.

I think it's a wonderful idea! Might not be economically viable, though.

I agree, but on a road course, without the low speed acceleration (1st and 2nd gear lets say), we shouldn't be seeing too many traction problems in the rear, especially with a 245+ R comp.

I guess we'll just have to see. Not being able to rotate tires makes for significantly shorter tire life in my experience though.

I'd try and run 17" wheels as well if possible.

Agree. Certainly not buying OE wheels for track/winter setups! That will put me in the poor house quickly! :wink:

Hopefully that means i"ll make a good return when selling the OEM 18's!

Question:

Are the hub bores of BMW's normally the same front and rear?

I'm liking the idea of picking up either some older OEM or after-market 17's (maybe 4 rear OEM wheels in the 17 x 8/8.5 range if they will fit) and running 245 40's or 255 40's all around.

I think simply changing the fronts to 245s will induce oversteer as the front will grip too hard. I am planning to use 225s for the front for track use. It's hard to say without experimenting.

you definitely would not get oversteer. it may help the under steer a bit but it would take something more drastic than a little extra tire to change the balance of the car that much.

Would throwing on a whole set of evenly sized tires for winter set up require a camber adjustment, in your guys' opinion? I'm a little new to the adjusting suspension thing.

No, you wouldn't have to touch the camber if you didn't want to.

Personally, I'm planning on 8.5"s all around with 245s. I might be worried about rubbing in the fron with 255s, but I'm not sure how much room to play with there is there.

Also, I use Yokohama Advan Neovas, with tend to have a very wide tread/section width for a given specificied width, so I'll probably stick to 245s the first time around.

As for wheels, it depends what will fit the car. I love the enkei RPF1s I have on my S2K, they've held up very well, if that won't work, I'll probably use Volk RE30s, as they're not only light, but exceptionally durable, and available in +42 for 18x8.5s, which I HOPE is good enough to clear.

Its not uncommon for BMW's to run non-staggered I'm assuming?

I'll try 17" wheels though for the tire budget, and definitely R comps (so hard to go back to street tires )

Ditto. If my existing 255's won't fit, I may try out the Bridgestone RE-01R tires, which are supposed to be very good as well.

I've heard very good things about their performance, both street and track, wet and dry, but haven't driven them myself. I have a hard time trying something new, I love the Yokos too much.

I'm assuming the car will be STU legal (AS I'm assuming as well)?

I have a set of RE-01R's in 245/40-17 that I got last year at Gingerman. I used them for three days at Putnam and one at Texas Motorsport Ranch and drove them in between on the street.

Good stick and very consistent for a street tire. Wear is impressive as I have just about 2/3 life left. The Bridgetone guys said to expect grip all the way to the end and we will see. Most tires I have used in the past for all around work get hard as a rock after about 6 track days and street driving. They do tend to be temperature sensitive and go away if pushed hard for about 15 to 20 minutes. If you back off for a lap or two, they seem to come back again.

So far very impressed with them and the price was really cheap at $165 per tire in that size.

Nope. No twin turbo in STU. Probably will be AS, but I've heard possibly BS as well. If it's BS I'm getting one. If AS, I think I'll go with the STI. Good idea?

Ahhh, silly me.

I agree with that. I think at its weight, with no LSD, it'll probably struggle in AS. Can't see how its going to be able to put enough power down in those low speed corners. The 335 have shown that to be an issue. Certainly could be a real good BS car with a big front bar and some meatier rubber....

The Cayman does ok with an E Diff. We'll have to see. I'm thinking I'm going non staggered as step one, and hopefully that gets it good and neutral.

I don't think the eDiff will be that much of an issue on the track at all. You may have to be a bit judicious on laying on the right foot, but so do other high powered cars. Where I do have concern is on the autox courses. I'll be running the 135i at the 4/27/2008 autox series kickoff event, and find out firsthand.
