I will run high 12's with these wheels and tires. The only thing stopping me last time was 20 mph sustained winds, with gust up over 30 mph, driving straight down the track.

I would suggest the set up for anyone who doesn't want the slicks quirm, but wants the best hook up with a drag radial. The RX7 wheels are very light, 13 lbs, much lighter than the tire themselves even, which come in at around 27 lbs. The combination should save around 10+ lbs from the factory set up too. I cut 1.8's easily, and with a little more practice on a slippery track, I could have run 1.7's. Those should be easy to attain with a track that is well prepped. Everyone except the guys on slicks and MT DR's was spinning pretty bad on this track. I have run slicks, and these are almost as good, and far better than the Nittos.

 

hey how much would this setup run for.

BTW they look very thin from the rear shoot

 

those or if you could get a set of 16x7 mustang waffle stars

they are very light and you can slap some slicks or DRs on them

 

FYI-there are 2 versions of that FD rim, one weighs 13lbs the other 16lbs. Both light, just wanted to let you know...

 

but arent they 2 thin

 

^^No why do you say that? Wider isnt always better. A 245 DR is way better than a 275 street tire. At the track you want to use the smallest possible tire that you can hook up with to keep weight down....

 

They are wider than the factory tire set up.

The contact patch is over 9 inches wide, and the width is 10 inches, versus 8.5 inches and 9.3 inches for the stock wheels and tires.

 

The MT DR's cost around $150 a tire, and the wheels can be had pretty cheap, since they have been around for some time. The wheels are going for around $100-$200 on average, and can be had cheaper.


You are correct, I have the 13.8 lb version to be exact. Just check for the version, PFD Cast (Brittle).

 

Ok thanks guys

 

I should add that the tire width on the stock 18's is 9.6 inches, I earlier referred to the 17's.

 

if you go for the mustang ones, I have been able to get 2 pairs at separate times to mount slicks on for free.

make a friend to "borrow" them from or get a set for dirt cheap, like 50.

I sold my stock set of 4 with DRs on them for 100

 

Those will fit my car perfectly...you change tires at the track or drive on them all the way there? I will have to borrow them next time.

 

I change them at the track.

I am going to try and go one more time before it gets too warm. I know she'll go 12.9 now, and would have at SGMP if we weren't driving against a gale force headwind all day!

I'll let you know when I'm going.

 

I didn't realize those rx7 wheels were that light but I should've known I remember Mazda marketing its light weight, etc, etc.. I just found a pair of 16x7 v6 mustang wheels and are about ~17lbs, the 15x7s are a little lighter. Both can be found very cheap and sometimes given away.

Alberto or veetec should i go with 17 or 18 with DR's or slicks i dont really know about wheel and tire spec

 

You're not going to find a 17" or 18" slick so your decision is a simple one. 17s would be superior for drag racing all else being equal.

 

I was asking this question becouse i was thinking on buying the rims maybe usind DR's for now and then later on when i need more traction get slick's.

 

The re-enforce rx7 wheels are the heavy ones correct which r the light ones the 16 or 17's im going to buy them

 

there are a set of 4 of the rims like i talked about for sale for 100 here if anyone wants to split them

 

Any pics? If they r the 13 pound version then i would be very intrested.
