I sometimes get the feeling I've got bicycle tires for rubber compared to other Porsches so I'd like to consider something more aggressive and intimidating.

I'm looking for input for tire sizes and suggestions for lowering the car.

Thanks.

Merry Christmas..

 

Are we talking about for street applications only?

 

I am looking for street only, atleast until I get the bug to get on the track.

 

I was very happy with the Michelin Pilot Sports on a 930. Expensive but good tires.
As to size, use the biggest tires that will fit. I used F: 225x50ZR16 and R: 245x45ZR16.
On my current wide-body race car I use 245x45/17 and 275/45x17 so that will fit too.

You may also be suffering from worn out shocks/struts. I found the handling much improved in my old 930 once I upgraded these parts.
Good luck
Chris

 

You can run 205 & 245's on your current 6&8"/16 rims.

For a max set up. 225 & 255/17's on 8&9" rims is a good fit, big wheel set up.

 

I have 18's on mine 225/40 on the front and 265/35 on the rear.

 

Lowering the car is perhaps better done by pros depending on your "DIY" skills. While not necessary overly hard, if the rear torsion bars have never been replaced in the last 20years, you could have quite a bit of additional effort infront of you.

A popular ride hieght is the "row" or "euro" ride height. Its likely 1-2" lower than your current "US" ride height.

Of course, while you are in there, several questions crop up like
1) What is the condition of any bushings?
2) Is it worth upgrading anything? ie stiffer torsion bars? new shocks? rew OEM rubber or aftermarket bushings etc etc

Tires? With 6 and 7" width rims a 205/225 combo is typical. If you have 8" rears, you can go to a 245-45-16 rear tire. Availablilty is a killer for 16" rims. 205/225/245 are your main choices. Or, you can spend more money and change to a 17" or 18" rim

One advantage to your "bicycle rubber" is a relatively soft "street" ride, which may be nice depending on the smoothness and quality of the roads you travel.

 

Speedlines, Fiskes, Turbo twists, Widened Fuch style. Too cool.

What I have done is run the softer compound tires. Pirellis have always kept me fro getting carried away. The above wheels will look mean and perform better.

For a while the CUP I was cool for that car but I think I have seen Turbo twists on narrow bodys. The speedlines are awesome.

Regards,

 

Ideally you would want a set of 7 & 9 X 16 rims with 205/55/16 F and 245/45/16 R

 

Remember your '88 Carrera doesn't have power steering. Go with very wide rubber and you'll really wrestle it at lower speeds.
I like 205/245. Narrow in front for better steering precision while the rear rubber's plenty wide enough for grip.
Now if I could only find more tires to fit 16" Fuchs...I'm never changing my wheels. They're just too pretty.

 

I just upgraded the rubber and fuch wheel combo on my car this year. I bought Fuch 8 by 16's and mounted 245 bridgestone re-01-r tires. I also did 29mm and 22mm hollow bar torsions with new factory rubber bushings. I replaced the shocks with Bilstein sport in the rear and HD in the front. I then did the turbo tie rods and new ball joint....then lowered it to euro ride height and aligned and corner balanced it. I have to tell you...its a night and day difference. Not only does it handle like its on rails but it has the fantastic stance that really make the fuchs seem even bigger than they are. Thats my recommendation...as the new bars didn't make it too stiff for the street.

 

225 F and 255 R Go with PS2, tirerack have a amazing price for them now ! i just bought a set !
