Look at the tire size. Whatever the "R" is on the tire size will tell you how big the rims are. stock tt is 225/45/r17. r17 meaning that the rims are 17inches. That pic looks like 19 inch rims. As far as the chip goes, test drive another 225 that is stock and then compare them.

 

i believe its 225, it has dual exhaust, 6 speed

 

I would try to get the stock rims back.

 

I'd say, those rims are 18", I hit curb on my right side and I paid like 195$ for refurbishingtwo wheels ( they did really good job)

 

who do you think would re do wheels... just curious, i have a few scrapes on myne and am looking to get them re done to some degree. thanks.

 

I don't know what state u r from but I had it fixed and refinish my OZ wheels ( looked like after like from factory) here in NC, Salisbury, If you need the exact address just let me know..

 

back to my questions, is it really necessary to have a boost gauge? if i put one, would that void my warranty (100k)? how would i find out what chip it has? and pitrman, how much did it cost to get your rims fixed? i live in socal btw.

 

The rims are 19'!

 

Boost, that's our power! so it's good to know what psi you are runnig at.chipped cars are of course running at higher psi (cca 20-25psi) depends on mods... Not sure for 100%, but I would not be affraid of loosing a warranty due to boos gauge... And I paid 195$ for two wheels9 in the post above)
good luck with yout TT

 

is there anyway of finding out what kind of chip i have in my tt? and where can i get a good boost gauge that is not to expensive?
