Default M/T dr M6 peeps chime in

Ive been doing some searching and found out that your not supposed to use m/t et dr's on m6 cars. But I havent seen anybody post yet that has done this and had a problem. So could you post if you have these and a m6 have you had any problems or know of anybody who has?? Thanks Troy

I have them on my stock M6 SS that dynoed 327 to the rear wheels. I've been 12.69 on them. I generally launch around 3500-4000 with them. I've even launched off the rev limiter once before. I haven't had any issues. The clutch slips before anything else so no breakage or ill effects and I've got at least 40 runs on them.

I run them on the street and track. No problems. Haven't got to play with the new 325/50s yet.

The only thing I would worry about is snappin the 10 bolt. I broke mine on old *** 245 nitto's with just bolt on power. The rear only had about 15k on it, and had an Eaton posi with a TA girdle. Id look into buying a beefier rear first, M6's beat the **** out of 10 bolts.

If you bust the 10 bolt then that's a good excuse to upgrade.

thats why the 6 speed guys go with a slick. but there are some guys pulling good 60fts on the radials still, just depends how fast you want to go

The 255 50 16 MT Drs didn't like the Exo Skel twin clutch at all . They would just spin anything over a 3,000 launch. And even then I couldn't go right to full throttle.

I forgot to mention mine are 255/50/16's. I wanted 16's so I could get more sidewall but not have to go to 15's and have to grind my calipers. I also run them at 20psi at the track.

you dont have to use a Slick so to speak.. It is recommended that Manual cars use bias ply tires not radials because of the softer sidewall.. it just so happens you wont find a slick thats a radial..

So it is recommended (by mt) that m6's cars use the et streets not the et street radials, and for that very purpose.. You cant load the suspension, its one quick jolt.. Somethings gotta give or youd like light them up..

Don't listen to that. Used properly the MT DRs are amazing on an M6. On a well prepped track I've dumped the clutch at 4500rpm and dead hooked. If the prep isn't as good you have to learn how to slip the clutch very very quickly at like 4000-5000 rpm.
