I have a 1988 Mazda RX-7 Convertible. What's the best size wheels to run on this without any real modifications. Secondly I was just given this car and everything is stock except I just put in the K&N Air Flow Kit any other Recommendations on any simple upgrades for a car dumby? THANKS!!!!

 

Upgrading the exhaust will probably be your next step, or you're not going to realize any benefits from the intake mods...Tires? That's mostly personal preference...

 

if you don't go over 17 inch by 7.5; maybe 8 you would have any rub

 

what do you recommend for an exhoust

 

Exhaust = Racing Beat (reliable source of rotary related parts)

Tires = Depends on rim size. If you are sticking with the stock 15" BBS rims, then a 215/50/15 or a 205/50/15 would give you some sick cornering and all-around handling.

I am sticking some 215/55/15 Kumho tires on my 88 this fall. I am upgrading from the stock 4-lug 14" wheels to a 5-lug conversion and some stock 15" GXL wheels I am cleaning and painting. The 215/55/15 tires will leave my speedo exactly at factory spec, so I won't have to think about compensating up or down for actual speed.
