OK, I searched earlier posts but did not find any mention of turbo rims, only Carrera C4S, etc.

I have a line on rims off a 2007 turbo. Will they fit my 2001 996 turbo without any problems?

Thx!

 

No as the 4X4 ratios are different

 

this makes no sense. Please explain. The wheel diameter is what matters. The 07 wheels are 19's, and as long as you have equal diameter tires you should be ok. In fact there are several people in here in the past who have gotten newer 19 inch turbo wheels.

 

someone on here bought a 996 turbo maybe a month or so ago and it came with 997 wheels, looked pretty good

 

I bought my car with 997tt wheels and have had no problems in the year and a half of running them. The ratios are fine for the front differential. You will need spacers in the rear though. My car came with 6 mm spacers in the rear and that wasn't enough as there was some light rubbing on the inside plastic fender liner. I recently installed 18 mm spacers in the rear.

 

I use 996TT wheels as my track wheels they work fine, so it should work the other way around too.

 

i have a set on a 04 turbo, plug and play.. 3000 miles no problems.

 

They operate fine without any problem...

 

I just removed my 2004 996 18" rims and replaced them with a set of 997 19" rims off of a 2008.

They seem to fit perfect and look awesome! Will have to post some pics, need to download them off my camera.

 

Thanks for all the replys. I'm going to get them fitted tomorrow. We'll see how they look!

I had a 2001 996 tt it came with 07 turbo wheels. The car ran good!!!no problems..

Sold car for a moded one.....

 

it has been discussed before. the actually wheels fit fine, but you have to watch out for tire ratios. you have to play with tire sizes and brands to find the safest setup.

Great! I read that entire thread on tire size differential and now I'm spooked. Almost too much information.

The tuner I'm buying the wheels from mounted them today and declared the 997TT 19"stock wheels a fit for my 996TT. They very carefully checked tolerances and measured wheel width and offset, etc.

The rear wheel is actually the exact same width as the old one, 12". The front is a 9" vs 8" for the old one. Offset on the front was the same. The rear differed by 1/8", but his feeling was I would have no clearance issues.

That said, when I asked if I should go ahead and order the tires (from Tire Rack) as if I was buying for a 2007 997TT, he suggested I call Tire Rack and discuss with their upgrade people. He felt they knew enough to make sure I got the right size as they recommend.

My concern is, do they know enough to make sure the diameter differential is ZERO, which would certainly be my preference?

This is quite the conundrum. I do not want to fry my differential.

 

damon at tire rack is a sharp guy give him a ring.

 

Here are some interesting facts on the stock tire ratios;
(From Tire Rack Spec sheets)

996TT stock tires - Mich Pilot Sport 2s
- Front 225/40-18, Revs per mile = 829
- Rear 295/30-18, Revs per mile = 832
Differential = NIL

997TT stock tires - Mich Pilot Sport 2s
- Front 235/35-19, Revs per mile = 817
- Rear 305/30-19, Revs per mile = 788
Differential = ~1%

Is there some change in the drivetrain on the 997TT that allows this 1% differential not to cause any damage? Or is 1% inconsequential?

Inquiring minds want to know.
