Searched and couldn't find anything.... Anyway I have major traction issues on high boost and cannot plant power till 80mph and this is when its over 80* outside. Lately I cannot plant any power at all till almost over 100 I am running 19 x 8.5 up front and 19 x 9.5 w/275 meat in the rear. I was wondering if anyone has run a 18 x 10 front setup and 18 x 12 rear setup. The wheels I am looking at are CCW Classics & the tires are BFGoodrich drag radial's. I only drive the Z in sunny weather and as a weekend toy so Im not worried about the short life of the tires or rain. Anyone have any imput? I should also reference that if possible I would like to have immediate traction out of the hole or atleast traction in 2nd gear with my setup. I further do not want to do a 3.3fd for the simple reason I love the way the car is now and have no desire to change its current form.

 

345 seems like overkill, go with a 305 or 315 setup on a 18x10 rear wheel. From there I can only suggest making some suspension setting changes as a tire change is not going to be the cure all.

Good luck!

 

I could be wrong but I dont think you can go wider than 315 without fender flaring. Of course cutting or rolling inner lip will be required.

I had a set of Enkei's that were 18 X 9.5, 10.5" that you can run 275/315's on with minor fender work. Im pretty sure a 315 DR would help you tremedously. Offsets were +30 btw.

Sucks I sold the rims before I ever mounted up some rubber.

What is your rear camber OP? Last time you had an alignment?

 

I am not sure what my rear camber is, last time I had it aligned was in April when I first got in on the road after the build. I have never really payed attention to anything like this before....now it has my attention ha. When speaking about rolling fenders in the rear though, what all is involved with that?

Suspension wise I am running Tein S tech spring & everything else is stock. Ideally I'd like to keep it that way.

 

OP, I bought a new fender roller this year and rolled my fenders. It's not difficult, just time consuming to keep from cracking your paint inside the fender. I'm not far from you either. I'd have your alignment checked and see if you can get your rear camber closer to zero as that will put a wider contact patch on the ground instead of running on the inside tread of your tires...someone please correct me if I am wrong.

 

Put these tires on the car and call it a day.

 

Unless you have a widebody, 345's are going to look ridiculous IMO. It's going to look like you have one big *** long tire from fender to fender. Think unibrow.....

 

You need to find that spec sheet and check it out. Going from -1.5 to -1.1 made a huge difference in my cars traction. Like I said, do a 305 or 315 DR, put that camber at -1 and you will be almost using 1st gear on the street, 2nd should easily hook with a setup like that.

Rolling fenders is easy, just make sure you use a heat gun to keep the paint from cracking.

 

running 345 rears, best performance upgrade I made from 295 I had previously. You can have all the power you want but if you cant put it down then you just wasted the 10-20k you put into the engine.

 

Thanks Alberto, I'll be looking into this now.

 

FWIW you'll have a hard time getting less than 1.5* camber with a 305 on a 11"rim with a +24 offset with a flat rolled fender. thats about as positive as i could get with only a few mm between the tire and the fender. so make sure you do the math before you buy new rims.

I guess it also depends on how much you are dropped.

For now, on your 9.5" rim I'd look at the MT 3782r drag radial. I'd skip on the BFG dr's. just not that sticky.

 

I do run an 18x10 front set-up, but have only gone 18x10.5 in the rear with a high offset and a 305 tire. A 315 could have certainly fit.

What kind of tires are you running? Tire brand/age is way more a factor than tire width.

 

+1 im on a 305 +22 with fender rolled dropped about 2 inches... its really close 315 would rub on my setup.

 

Wondering whatever happened with this setup. I'm currently running an 18x10/11 +27/+25 with 265/295 tires respectively. My fenders are rolled and flared quite a bit, 295 tucks very nicely with a little room to spare. Just thinking ahead to my build. Shooting for a solid 600whp and want to put as down as possible. Due for a set this spring anyways
