I was looking at going wider but I want to stay with the stock style rim. I found many replica ones but all 9".

I ended up calling one of me and he advised that they will have a 10" model available in about 6 weeks.

So this may be another option for you guys.

I already have my 18" Nitto NT05R drag radials for the track but have a replica 10" and thought on a wide performance summer tire is appealing

Don't HC rims weigh 30 lbs? Not really light...
HC rims are forged alum and reps are usually cast alum I can't find the weight but HC was in the mid up 20's and the cast should be mid 30's in comparison.

CDN,
Does an 18 in rim fit over the rear brakes? If so what brand rim are you using?
Fits over brakes but you can only go 10" wide without relocating the sway bar.

As for weight yes forged is of course lighter but we are only talking 20 to 25 pounds overall and frankly when I'm racing I would rather put a tire on a rim size that is recommended.

I know guys are fitting 305's on a 9.5 rim and have no issues but if they had an accident and a collision investigation was done and the tires were the causal factor, liability wise you would be, as we say up the creek without a paddle.

I went with a different style of rim 18x10 and the 305 fit as well as the wheel well.

Theses new rims may be a great option if keeping a stock appearance

Well this rim match's. In look but I like an 18" better for the track as I get more sidewall. I'm using the Nittor NT05R. They are great but boy do they not last as they are soft.

I found 18 to 20 lbs was best and about only a 7 or 8 second burn.

I didn't drive with these daily as they are dangerous in the rain.

No if you plan on having them on the street more often then the NT555r is good too but not as good as the NT05R at the track.

25# is huge! Look for every pound you can get off this fat cat!

With the Nitto you have two choice

305/45/18 or

305/35/20

The 35 and 45 mean percentage of tread equals sidewall height.

Having the higher sidewall with low air provides the flex during launch for increased traction.

People can say what the want but there is a noticeable traction difference between tire sizes with different sidewalks.

Good luck on finding what works for you.

The Nittor NT05R comes in a size for the 10" rim and if you are only at the track you could try and risk it but Im not willing too that is why I think they replica will be great for the track especially if you are trying to keep the look.

The rear is the easy one to get. You can do 17x10, 18x10 or 20x11. First two you can get from Bogart, Weld or CCW. All lighter than stock. The 20x11 is available at Tire Rack about same weight as stock and looks almost like stock. http://www.hellcat.org/attachments/niche_circuit_blk_rw_a3-700-png.2027/

Search bigger wheels on here.
CCW and Hemituner are working on front/rear lightweight wheel packages

Thanks guys. I had no idea a 17 would fit out back. That's all I really want.
Before you get 17" out back check tire size 29" MT or Nitto only make 28" in 17" but you can get 29" tires in 18" FYI

I would stick with an 18" rim for now as we can't tune the cars yet and if overall tire height changes too much the car will go into limp mode which sucks. I know as I forgot at the track one night and it was not fun.
