I want to install Volk GTC 19x10.5 on the rear of my 2003 Touring. What is the proper offset? I want them tucked inside the wheelwell, and I dont want to roll the rear fenders....Thanks...

 

The correct offset will be 19x10.5 with 29 offset

 

Running 10.5 rear's.... +29 offset ...

If you wanna see how the tuck go to my Journal.

If you get TE37 10.5 rears and 9.5 fronts, the off set is 22. But I think for GTC, it's 29.

 

Your car is awesome. I am getting the same wheels and I have two questions for you!

1. Will your size and particular offsets fit a model w/ Brembo brakes?

2. In your album there are no side shots. Could you post a side elevation shot or e-mail one to me? Thanks

Really sick ride!!

 

19x9.5 would have a +21 offset and the 19x10.5 would have a +24. That is what works and what the reccomended size is. Let me know or give me a call if I can help you with any further questions or if you would like to place an order. Thanks!

Is it possible to fit 10.5 in the rear without rubbing on a Eibach drop?

 

If you would like pictures of the wheels I can email them to you, let me know!

 

Unfortunately, I don't think it's possible to fit any GT Series wheel in the rear with a 10.5 without rubbing. To my knowledge, the only wheels that work in the rear in a 10.5 without rubbing are the TE37's and LE37T's in a +35 offset. People really shouldn't be afraid of rubbing though, all you do is take your car to a reputable body shop, leave your car with them for the day, and pay them anywhere from $100-$200 and you are all set. You won't even be able to tell that your car was even touched. It's really no big deal at all; just my 2 cents

As you can see from my Journal ....

http://journals.aol.com/mdelacruz2/T...dri/entries/58

......my car is dropped 1.5 inches. I did not use the Eibach Springs, I went with Espilar. No rubbing at all. I did NOT have my fenders rolled by a body shop.

I was not aware that different wheels required Different Offsets. I've never hear of that before.

Offset is the distance from the Centerline of the wheel to the wheel bolt up face (the part of the wheel that contacts the car's hub when you attach the wheel). Positive or Negative is the descriptive term that tells us whether the wheel bolt up face is farther towards the inner or outer part of the wheel.

For me, I contacted Jeff From evolutionautosports.com . I found him to be an EXPERT on proper ofsets and Rays Wheels in general.

For what I wanted : No rubbing, and the wheel to be flush we went with these offsets:

Front 19x9.5 +19 offset

Rear 19x10.5 +29 offset

Joust...

Thanks for the compliments....here are a few more shots of the car...

I'm not a wheel expert, and there may be a difference in the GT series wheels and the GramPro Lights that I have... I would recomend consulting a good Tuner.

 

With our company being the largest distributor for Rays/Volk Racing wheels on the East coast, I figured I would share some information with everyone

Jeff must have misinformed you, or you must have misunderstood him, because the difference in offset actually refers to the distance from the center of your car to either side of the car. This means, if you have a +21 offset on your car in the rear and you want to go to a +29, it will adjust each side of the car +4 mm for a total of the difference which is +8 mm. Therfore if you go from a +21 offset to a +29 offset, it is not going to push your wheels in 8mm on each side, but 4mm on each side for a total of 8mm.

Now on another note about different offsets being different for different wheels, most Volk Racing/Gram Light wheels, have at least three (and in some cases four) different pad types. High pad, mid pad, and low pad. The lower the pad and the higher the offset, creates a larger lip and little brake clearance. The higher the pad and the lower the offset, creates a smaller lip with much more brake clearance. Mid pad is usually offered to AWD cars if available.

The lower the offset, whether a one piece or two piece wheel, the more concave the center of the face of the wheel becomes, offering more brake clearance by allowing the outer part of the face to bend outward more. And as I explained above, the lower the offset, does not necessarily mean the more lip, it depends on both the offset and the pad type. Low pad + High offset = larger lip, High pad + Low offset = smaller lip.

Just thought I would share this information with everyone. It was not meant to be a flame post, but an educative one.

we've done GT series wheels in a 10.5 with a lower than +29 and lowered the car and no rubbing either.

 

mdracer76's explanation is correct. Offset does not refer to the center of the car, but to the center of the wheel.
