Say, I was noticing on your profile that you run 245/40s and 265/40s. I'm supposing that you're running them on your stock track wheels (and why wouldn't you be?!?
). Does this tire set-up not give the VDC fits? Any problems?Just quick reasoning:
225mm*.45 = 101.25
245mm*.45 = 110.25
= 9 (mm difference?)
245mm*.4 = 98
265mm*.4 = 106
= 8 (mm difference?)
I haven't seen many people running this setup. Usually it's the 275s in the rear. But it looks like your choice actually matches better.
245mm*.45 = 110.25
275mm*.45 = 123.75
= 13.5 (mm difference?)

Oh yes, the tire people hated putting those 265s on the rears. VDC works, most of the time. If I do some seriously spirited driving (~5-10 min worth), the combination of slightly wrong sizes, plus the Tein, plus the Hotchkis bars will make the VDC take itself offline if I haven't already. It usually works though. I just dont think that 275s would fit well on the track rims. Fortunately, the ABS seems to still work well. I should do some instrumented stopping testing to check that out though.
Unfortunately, for spray or the FI I dream of, I'm gonna need something like 295-315 out back. With all the weight out of the car and the Tilton, I just don't have traction until 3rd NA, or 4th with spray on the roads down here.

Why do you guys think the car is faster just because you increased the redline? lol, The hp and torque curves are crashing past 6200. Your engine is as weak at 7100rpm as it is at 5000rpm, it cant breath at that rpm! its better to shift into the next gear at 6500rpm, and be in the power band. DUH!!!!

you don't understand the concept of gear ratio's and if someone has a lot of mods to actually shift their power curve to be up that high
JWT cams, crawford headers and cats, SSV manifold etc will raise your power curve quite a bit and orient it for more power between 6000-7000 rpm's
