I have gotten a 1.78 short time on my Nitto DR's but my car only makes 275 rwhp so I won't do much better than that...

I've never been brave enough, or is it stupid enough, to add up all that carnage but it did go 1.34 dead hooked when it didn't break

BTW, the last year I had the D44, I broke the rear 5 times

Hope you guys have better luck,
Dave

yes that was my reasoning

My observations have never seen the sidewall distort enough to compensate for the outside lift during camber change.After a run my tires show visible marks on the inner half with nothing on the outer.
The camber change on launch can be dialed out by changing the chamber setting but then it would be wrong for stret use.
well it was just a thought.. and i was using et streets as an example of a tire with a wrinkle wall.. just wondering if have you played with tire pressure? i know with my camaro and et streets i could wrinkle the tires quite a bit to the point where the rims were very close to the pavement but that is apples and oranges and just thought if you used a tire with a bit more sidewall and around 15psi you may acheive a better contact pad in our cars.. but i don't really care to put the effort in that much... and as i said.. just a thought..

You can do things like the DRM extragrip w/ relocated camber rods (less camber change during squat) & reduce the toe??

Repeat after me: "Race it, break it, fix it, race it"....I broke my Dana 36 about 4 years ago (no big surprise) and put in a Dana 44...over 600 passes since then without any breakage of anything...

The old story will never change...Speed costs money so how fast do you want to go?...the faster you go the more stuff breaks...same old, same old...
