4.10'S, RPM's spinning too high! what size tire do I need???
Went to the track for the first time with 4.10's and found myself spinning 6600-6700 at the end of the run in 4th gear, which is a bit high for my taste. I'm running stock 275/40/17 and have an M6 and the car is lowered with Eibach springs, the smaller of the two kits. I checked the fbody.org/gears site, but it said I should only be at 6100 RPM's @114mph, but the tach definitely read 66-6700.
I'm also looking to run MT street radials on a smaller rim. What overall diameter tire should I run to lower my RPMs enough so I'm finishing around 6300-6400, 6500 tops keeping in mind I need to stuff into a wheel well of a lowered car.
Also, are there options I'm not considering that would make me better off???

get your self a 27'' tire if you want to drop the rpm's. the 27'' tire needs no mods to fit. i run the m&h racemaster cheeter slicks. i've tried m/t's and hoosier,the m&h out hooked both of them for me. www.intercotire.com. if you don't see the 27'' call,they do have them. goodluck to ya.

It's the stock one. I was thinking that myself, and just started looking into getting an aftermarket. It seems to match up pretty close to the shift light though. I also just found out, I may have been letting off later than necessary to finish. The track in Dallas finished a bit past the time signs and a light flashed, sounds like this track finishes right at the sign. Either way, I still want to shove as much sidewall in a lowered vehicle as possible. or look for suggestions of spring selection at a higher height with a bigger tire.

Well, if you want to swap springs I would say go with a set of 93-97 v6 springs. They will allow more weight transfer, and also give you bit more room for tire than you have now.
