I have -1.95 up front with the Dinan plates, and I think that works great. It is questionable if you need more, but then we haven't seen anyone reporting running with more up front. There is more discussion on camber settings for the track here: http://www.m3post.com/forums/showthread.php?t=258968

Yeah, I see, pretty touchy through there. All those guard rails closing in make it seem even tenser.
I wonder if you could try two short-shifts to get up to 5th by your final shift and then compare your entry speeds onto the straight that follows. The toque curve is so good that you might do better in fifth at WOT than you think. It'll start a little slower, but you'll continue to accelerate through that period where you're against the limiter. An alternative is skip 4th and compare your speed at the beginning of the straight. Dave

Had two track days on it at those settings. So far so good. It's my DD, so I don't see myself going more aggressive than that at this point. Keep in mind that's with a staggered 265/285 setup on the track, and a staggered 255/275 setup on the road.

I'm on my stock 18's - 245/265 track and street. Think that will change the numbers a ton? Should I just be telling the dealer -1.95 up front and -1.5 in the rear? Toe, etc all stays stock?

I drove my DD 5.0 Mustang LX knotchback with zero toe. It was a rough riding car already, with lowering springs and Tokiko's super shocks, so I put up with the extra dartyness. I don't think it's worth it with the M3. The 'stang had weight distribution issues, so it was worth it in that case. Since the M3 doesn't really have turn in issue, I wouldn't be interested in doing it except on an all out track car.

I bought HR springs and haven't opened them. I've changed my mind and I'm going with Dinan. I have Macht Schnell spacers on my car and that made a big difference in the look with the stock springs. The .5 isn't much but it will do enough for me with the spacers.

My best lap at VIR looks so smooth except where I go over the curbs in the esses and that's only a little rumble in the audio. I'd missed an earlier apex just a tiny bit and used the curbs to straighten the track. There's a little chirp from the tires at the end and the audio doesn't catch my sigh of relief. Dave

Putting shorter springs on a well dialed in car is likely to result in some loss of ultimate performance unless a lot of time and thinking goes into the new spec. The current suspension spec was probably dialed in after hundreds or even thousands of track hours. Dinan probably spent the most time thinking about the product, but I doubt they spent that much R&D time on a track at over 9/10ths hour after hour making small tweaks here and there. |
