Thinking of a way to widen the NB E88 wheel to a WB spec. There are two ways to do this.

1. Both inner barrel and outer barrel.

2. Just the outer barrel but the wheel will be 12.5" wide. Would have to get a larger tire to accommodate the wider wheel.

Leaning towards the outer barrel only to save a little cash since the inner barrels are close to $600 each.

Anyone with any insight on what a good tire to run and will I also have to change the front tires and rim width which I don't want to do, or is this not a good idea and should I just do both inner and outer barrel?

Thanks for any input.

If you shoot me what you are working with:

Center part number
Size of current outers
Size of current inners

Can put some scenarios together for you

Please email eric@supremepower.com

Need tire size recommendations.

997.1 GT3 RS

19 E88's

Fronts 9"

Rears 12.5"

Will 997.2 GT3 RS tires sizes fit on a .1RS without issues? Just concerned with the fronts.

I have a better idea. Sell me your E88s and buy a new custom fit set for you.

Same idea but to me instead since I'm local

I have a solution for you, I converted a wide body set to narrow body and still have the complete inner and outer wheel halves for the wide body configuration. Unfortunately their 18” not 19” though…..

Someone give me enough money and they will go right out of the garage. They are shod with Pretty much brand new Cup 2's. Maybe a 150 miles on them.

No tire choices in 18's.

I've noticed this lately too. It's either really bizarre, or I'm out of touch with the market. I used to be able to get any performance tire in 18's and now all I can find are Nitto NT01s and Toyo R888R. Neither of which make good street tires.

Typically tires you can run on either 997.1 or 997.2 RS
245 35 19
325 30 19

Can help more if you send me the offsets or the center part numbers and we can see the propsed lips and barrels and what they will make for an offset

If you're just driving around, just throw some spacers on them and call it a day. Then can you decide if it's worth rebuilding at a later date.

RAudi Driver

i can’t do that. That would require a 22mm spacer

What size were your original wheels?

These are ideal specs for a narrow body car:

Front
E88 274 center
19x9 +50
1" lip
8" barrel

Rear
E88 108 center
19x12 +62.5
2.5" lip
9.5" barrel
*Remove factory spacer

To convert rear to Wide Body fitment:

Rear
E88 108 center
19x12 +50
3" lip
9" barrel
*Add factory spacer to lower offset to +45

I went up one size to 245/35/19 up front, paired with 305/30/19 out back. I think this is ideal for a 3.6. Fronts fit without issue.

.2 GT2 and GT3 RS both run 245 and 325
.1 GT2 is running 235 and 325
Someone more in the know can confirm, but I believe these cars are also set up with more rake and stiffer rear bars.

If you're going to spend on bigger tires for 12.5 rears, why not just bite the bullet on 9" barrels and stick with 305s?

John, my narrow body .1 had the E88's in the exact specs as F50nut stated.

Working with Eric at BBS, he said there are two ways I can go.

The normal way, which is what F50 is stating with the 108's, is changing inner and outer barrels. The inner barrels are if I recall correctly, around $560 each. The outers are like $270 each. So an alternative is to just do the outer rears, changing the 2.5" lip to a 3" lip. However, doing this will turn the wheel into a 12.5" wheel, of which a 305 is too small. That's the predicament. Do I run larger tires on the back, at which point I would need to change the front tires also to keep the car in balance or do I bite the bullet and do both the inner barrels and outer lips and keep it at a 12" wheel? It's like a $2,000 change and that's not counting turning the gold into a satin black and the lips into a gloss black.
