RX7 rear tires ??

[Grumpy]

[V8Killer]

What year? 1st, 2nd, or 3rd Gen?

[Grumpy]

I have no idea ....it's an 88 RX-7 GXL

[DAVID C]

Dan, that's a 2nd generation. You'll want to register at www.rx7club.com . It's a very large group. Lots of info and classifieds. When it comes to tire combos. It's been beat to death. Still, no one agrees. You might want to keep the Buick part to yourself over there. They are die hard Rotorheads! Dave C.

Forgot to change my signature. That's weird. I just changed it, but the update showed on my last post.

[Grumpy]

hey I am looking forward to something different !!! and this def fits the bill Ill be talkin to ya !!

[V8Killer]

Hey Dan according to http://www.grannysspeedshop.com (look under misc. tech info), you can fit a 275/50/15, 275/60/15 on a 9" wheel with 6" of backspace, or a 28 X 10 slick if you roll the fenderlip

[Pronto]

Gonna put that Stage II in that? Al, how's your friends RX7's project? Is that where you got that info from? No info on a Caddy swap on that site That project is just plain sick.

[Grumpy]

13 sec car! Back with the mazda rear diff with 3.90s and those dinky 205 tires, I did get one pass in... 12.8 @ 107 (2.3 60ft). It broke the tires loose big time shifting into 3rd and blew the intercooler hose wide open with only 18psi! If I know you Dan you'll have it into the 10s in no time. Dave C.

......umm Dan, too late Let's see, a "stocker" Buick-turbo 6 in a 2,900 lb.(guessing weight) car, sounds like tens to me. Just add methanol and stir

and BTW, I was thinking the same thing a couple weeks ago, when my buddy picked up his RX.

[Grumpy]

no !!! not that light ..plus my fat ass will be 3500#s ... so 13s should be on the $$$

Check out the V8RX-7 section on http://www.torquecentral.com

That car will fly. I went mid 11's on a stock turbo in mine.

If you want matching rims the '89-91 Turbo 2 rims are 16x7 and weigh about 16lbs. You can put 245/50/16's and 255/50/16's on them. A better choice would be to run 16x8 '93-95 RX-7 rims out back (16lbs also) and the same size tire. They won't fit up front without hubcentric spacers. RX-7 convertible rims are only 15x6.5"; however they only weigh 11lbs each. 225/50/15's fit easily.

Scottie GNZ in FL can probably let you in on his preferred combo with the same style RX-7. He runs 16x4" space saver aluminum RX-7 front spares! Welcome to the world of sub 3,000lb cars, .29cd aerodynamics, and sleeper status. .

well Melissa went 11.4s with a stock motor with a 51 turbo and 50# inj .. this is prob 4-500#s lighter .. this is goin to be fun !!! now do guys put frame connectors and such in these cars ??
