Hi All,

I have a few questions about wheel fit on my 89 S4. I have searched the forum but cannot pin down what I am looking for, hopefully someone can help me.

I have a set of 17X7 rims 55mm offset with 205/50 tires for the front, and 17X8.5 rims 50 mm offset with 255/40 for the rear. I am hoing to fit these on the 89 but not sure if I should use/need any spacers? If so, will I need to change the studs, or get spacers with studs already in them?

I have a similar set of wheels on my 86 S (the fronts are the same, the rears are 17X9 with a 55mm offset, same tire as above) and they fit well with the 21mm spacer on the rears.

Basically, I am looking to find out the differences from the 86 to the 89. If I just get a set of 21mm spacers for the 89 will I be fine? Any help is greatly appreciated!

IIRC that is what my wheels are on the 87 (practiaclly the same as the 89) so they will fit no problem without spacers.

Porsche recommends a minimum of 225s on the front tires. 205s are too small

I thought the question related to the wheels. Tires are a different matter.

physically they will fit, they'll be close to the calipers and you'll probably need diff caps for the front to clear the dust caps

Thanks for the info!
