I recently mounted my old Breyton Forge GTRS wheels for narrow body C2S on my wide body 997.1 Turbo, the front wheels looking ok, but need 5 mm spacer to keep it looking flush. However the rear seem anemic and skinny mostly because it not WIDE enough. So I ordered 15mm spacer for the rear also, question is "does spacer will compromise with car handling? Also, running narrow body wheels with exact same spec 19x8.5 front and 19x11 rears on wide body car would do any damage to my wheels and tires? Those who have any experience please help.

 

A bit hard to follow your question/info hear..But from what I can see in your post I would offer the following:

1.) Assuming you have good aluminum Hub Centric spacers on your car to get the wheel positioned correctly, it will absolutely not hurt or affect your car.

2.) You say your wheels seem "skinny" but the sizes you indicate are correct for a 911 Turbo, so unless you put narrower tires, they should be the same with the exception of the offsets...which brings me to my next point..

3.) The offsets may be different on the wheels you put on. You should verify they do not go in too deep over the rotor that they hit anything..or on turning your front wheel. If that is OK (even by adding the spacers) then you are fine there too.

4.) Last point..On a Turbo AWD, you cannot jack around with the tire/wheel sizes without paying careful attention to the overall circumference. I think Porsche allows for about a +/- 3% margin or error between front and rear. Beyond that, you risk destroying the AWD differential/transfer case.

Hope that helps...And not sure which tires you have or offsets on your wheels, but here are the factory sizes/specs:

Front alloy wheels: 19x8.5" ET56
Tire: 235/35R19

Rear alloy wheels: 19x11" ET51 (so with a 15MM spacer it would be = to ET 36)
Tire: 305/30R19

therock88- I think the Breyton wheels have different offset for narrow body compare to turbo wheels. I gotta check on it. Thanks
If you look closely at the rear wheels, you can see it not wide enough to the fender line, almost like it tucking inside the wheel well

 

your breyton's were made for a narrow body 911 as your said. That would mean your rear offset is in high 50's or low 60's. You will need 25-30mm spacers for the rear to make it look flush on a wide body car. I would get rid of them and order wide body wheels just because of the thickness of the spacers required to make it sit flush.

 

Maverick- I took the car to the dealer mechanic, they measure at 15mm would make it stick out enoughy to look flush. IF it require 25 -30mm, I would definitely pass but at 15mm would it compromise anything at the wheels?

 

Yes...I see what you mean...And I agree with Maverick. To get factory wheels flush you need ~15MM Spacers, and that is with a ET 51 offset in rear...You look like you would need even bigger spacers...and then they are getting to the point where I might just get new wheels ....That is a big unnecessary chuck of aluminum and some really long lug bolts....

Also with the face being that shallow, those wheels are jammed way in the fender well and may start rubbing something? Nice looking wheels though! A shame they do not fit.

Good luck!

Thanks guys for your inputs. I already ordered the spacers yesterday. I am gonna put it on then repost the pictures for you to see. Merry Xmas gentlemen

 

Good luck! And Happy Holidays to you as well....

Every time I read posts about spacers I always want to know why would you guys be ok putting spacers on your expensive *** cars especially when you can get proper fit wheels? Not that anyone asked but I would never compromise my safety by using spacers no matter how well they said they are made

I understand your opinion Redwine, I am using this car only for weekend ride and I don't race or track my car. I am hesitating to put spacer on my car as well, however I have a spare set of Breyton with the same spec but different offset. I just want to know if these spacer would compromise my car handling or damaging my wheels or tires. But your opinion alway appreciate here.

 

Porsche has been using spacers for ever on the 911.
If they are of good quality there is no risk !
If I am not mistaken those Breyton wheels are fairly light. So adding some weight for the spacers will not upset anything. You'll still be lighter than someone with GT2/GT3 RS wheels.
And than there is the PPCB disk as well.

 

993S - thanks for your confirmation about spacers won't damage my wheels or compromise handling. If the spacers improve the look of the car, I don't have to spend money on HRE P40 wheels. These Breyton wheels are super light weight and forge, but will see how it works.
Does anyone here using ECSTuning spacers before? Any feedback or reviews on ECSTuning spacers would be greatly appreciate

 

I have ECS Tuning on mine but haven't had them long. They look like they are good quality and the great thing about the 997 Turbo hub and ECS spacers is it includes a replacement hub screw so these things are screwed directly to the hub. This makes tire changes a breeze and you don't have to worry about the spacer not being perfectly flush to the hub.

 

Thanks Brent, good to know ECS making high quality equipments, I don't want to buy any cheap China knockoffs products risking defective and my wheels falloff..... Anyone else have done spacers on your Turbo, or using ECS Tuning spacers please chime in.

 

There is absolutely nothing wrong or unsafe with running spacers on wheels if you know what you're doing. The stock bolts do not have enough thread so you would have to compensate by getting longer lug bolts. I am running the H&R spacers with extended lug bolts on a Turbo that has more than 3000 track miles and not one issue.
