Hi everyone,

I just purchased a set of wheel for my coupe 20x9 +18 and 20x10.5 + 20 and planning on running 225/35 and 255/35. Do you think i will have any rubbing with both front and rear?

Thanks

I was told that for G's the offsets need to be +36 to +48, the exception being the all wheel drives. I think my offsets are +43 on my sedan (I'm not sure its been a while). I don't have staggered rims though. My rims are 20x9. Contact a reputible rim shop and they should be able to guide you through it. I used Specialty Automotive Treatments in Fort Lauderdale and they work with mainly high end Sports / Luxury cars.

Here is the Phone number: (954) 462-3334
Ask for Javier, He's pretty knowledgable and there isn't a fee for info.

On second thought, If there is rubbing buy spacers to add up the offsets since you already purchased the rims and tires.

Thank you for the provided information. I think my offset is a bit aggressive now to add any spacers on. Maybe I m gonna find out after I put the set on. Just have to wait to get some tires.

Sedan fitment is more conservative, something that's flush on a sedan would be about 15mm (give or take) inside the fenders on a coupe. That said your aggressive offsets on wider rims will be a bit challenging to get inside the fenders. Your stretched tire sizes sound about right and with a deeper drop and some excess camber you may get them inside the fenders. Not sure what look you're after, might want to check this gigantic thread and see if there's some guys w/ similar setups.

I did look through a big giant lowoffset thread yesterday and was just a bit concern if any rubbing may occur rears. That car is actually my buddy's G. I actually saw it in person but has been a while and could not remember the exact look. Thank you for finding it blnewt, I ll probably ask him how to trim the rear brackets when the wheels are on.

I don't know much about the coupes. But Call that number tomorrow and they will be able to tell you what you'll need. They are good trust me. Anyway, glad to help.

As a matter of fact my Avatar photo was taken in SAT's parking lot after they did the work on my G.

Always great to have trustworthy shops and guys you can count on to help you out, it can be rare to find that these days.

No kidding. I went to 4 different shops before trusting my car to SAT. They had two bentleys and a ferrari in the shop when i came in. If they can stay in business for 17 years working on that caliber of vehicles then they definately can hook up a G37. (and they did) They were a little pricey but they garunteed all the parts and work performed by them. I had no knowledge what-so-ever about the fitment for my G. The guy I spoke with (javier) was like a walking encyclopedia on cars. He didn't even need to look up my VIN. It made a real impression on me, and I told them I would plug their business anytime I got the chance.

I have a pic on my phone of a porsche they customed to the hilt. I will upload it to my photos as soon as I can.

Here is the Porsche SAT did up.

I'm running 20X9 +22 with 245/35/20 all the way around on my 08 coupe with Stance coilovers. Only issues I had was the screw/bolt (can't remember) where the rear bumper connects in the wheel well. I did just purchase camber arms though, because my alignment lasted 20k miles, but fronts had a ton of life in them just horrible toe wear.

Nice fit and a great looking wheel for your coupe, looks like they were made to go together

I am about to order tires and just wanted to make sure if 255/35/20 tires will work for my rears 20x10.5 +20 or should i run 255/30/20. I dont know what issues will I confront if I run 35 sidewalls instead of 30. I searched but cant find anything on forum. Can someone please enlighten me some details ? Thank you.

Just gotta use the calculator, the ideal diameter baseline would be 245/35/20, so use that as your baseline and plug the 255 sizes in line two

You'll get the following~
You'll be about 1% off w/ the 35 series and almost 3% off w/ the 30 sidewalls, so the 255/35/20s are a much better choice.

Thanks Brad, the reason I asked because I prefer to have some meat in the rear. As I searched forum, 255/30/20s are mostly used for the rears. There are coupe people going with 255/35/20. I m not planning on slamming my ride but if I have to, 26 will be the lowest ( current 261/2 all around.) so I guess if I want it to flush I can go with 255/35/20 and need to dialin a bit more negative cambers, trim inner lines and bumper brackets.
