Has anyone put on larger tires and lowered car with D3 springs? Looking at 255/40-20 front and 305/35-20 rear. Any help would be great,don't have car yet. Its still a few weeks away, but want to order rims and tires.

yeah lots have done it. it fills up the wheel well. Get a hold of Nineball. he has his that way. Only issue is with a full load and a bump you might rub.

Ummmm... if you are going 20's, why wouldn't you use 35's front and 30's rear? we aren't driving trucks.

Only tire choice in those sizes at 35 and 30 are P-Zero. And I want to close wheel gap while maintaining some ground clearence and still have side walls! Roads are so bad here that you almost need a 4X4 to get around.

Then DON'T go to 20s, go to 18s!

No 18's won't cut it as a show car/ semi daily driver. 20's with higher profile tire will give me enough side wall to prevent wheel damage. Just worried that with lowering front tires may rub when turned?

Best bet is to lower it and stick with the stockers. IMO.

I was considering that, but when doing a car for mag coverage they all wamt to see bigger rims and tires. I may leave it until i get car to do some measuring,that was the orginal plan. But car is taking forever to get here,its been 12 weeks now and am told will be at least 2 more.

i guess I'll have to see the final product. I have never seen a bigger side wall on a 20" that looked good. I thought you always wanted to go smaller sidewall with bigger tires to make it look good. I think with your 20, and the taller sidewall as well as lowered will 100% rub. I have not lowered mine yet, springs are stitting in the garage, but I have seen several members here and when it's lowered and the stock rims it just barely looks like it will clear with no rubbing. I know on the other forum a shop lowered and put 325's on it and with 2 guys in the back it rubbed over bumps, but I do now know where it rubbed.

I have had many conversations with Ro from D3 and Scott from Forgeline concerning building a new set of wheels and tires for me. After putting a V Coupe on the lift and taking a lot of measurements....D3 says a 325 can fit without rubbing in the rear. I have decided on a 20" setup for my coupe using the GA3R wheel with a centerlock option. 20x9 fronts and 20x12 rears will fit the coupe. I want to ensure I'm not dealing with ANY rubbing or fitment issues so right now we plan on putting a 305x30x20(minimal slight stretch) in the rear and a 255x35x20 in the front. Not a lot of rubber available in those wheel sizes right now so I'm kind of limited. I hope Michelin comes out with a 315x30x20 in the new Super Sport tire. These should fill in the wheel wells pretty good. The wheels will have race gold centers, black anodized GT style centerlocks, black "unhidden" hardware bolts, polished stepped lips and satin black inner barrels. They will look a lot like the 18" wheels on the Ferrari below (cept' mine will have a single black centerlock nut vice 5 lugnuts and I will have black bolts on the outer diameter showing):

Ideally you want to keep the diameter close to stock specs if possible(speedo, etc.). So, a 305x30x20 and a 255x35x20 would be better for you. Just my .02

As of right now only tires made in that size is the P-Zero. Toyo T1R's are discontinued and I am told that there is no stock left in 305/30-20's.
