Spacers: 2001 Boxster base
 

I have a 2001 Boxster base with a set of staggered stock 18 inch Turbo Twists. I don't have a great deal of knowledge when it comes to offsets. My tire sizes are as follows: Front 225/40/18. Rear 265/35/18. I would like to use spacers to give me a more aggressive look/stance without rubbing, scraping or ruining performance. Any recommendations on what size spacers to use up front and in the rear? Suggestion and pics would be appreciated. Here's a pic of my car. :)

I'm also interested in making my car more of an aggressive look, I'm not sure I would like wheels jutting out of the fenders though,

Honestly, in my opinion I just think the stock rims don't look aggressive at all and would need a decent set of 18's to start. Then a louder exhaust to untame the beast

You might want to check this thread and just look at pictures of other cars before you decide on what you want to do.

from the angle it doesnt look bad. it may help to see a flush view from the side of the whee and wheel well. I have the same wheels and have a 7mm spacer up front and I think the previous owner put 15mm in the real but I cant remember.

What are the wheel specs (i.e. widths and offsets) ?

Depending upon how aggressive you want your fitment to be, as well as what your suspension set-up is, here's a basic outline to follow:

Fronts:

8 inches wide = offsets ranging beginning with +40 to +35

8.5 inches wide = offsets ranging from +45 to +40 or so.


Rears:

9.5 inches wide = offsets ranging from +40 to +35

10 inches wide = offsets ranging from +45 to +40 or so.

Again, these are based on a number of fitments that I have experiment with personally, and fitment between vehicles can vary based on suspension set-up, tire size and application of use.

For what you want to do, here is the easy way:

1- Place a long straight edge up and down touching the outside of each tire and extending up into the wheel well. Go buy a long rod or small aluminum shape at Home Depot if needed.

2- Measure the distance from the inside of the straight edge to your wheel lip.

3- Try a spacer matching the measurement in step 2. You can probably get away with more than this if wanted as the wheel travel on a stock vehicle will rarely get to the maximum tire overall width, and the supension will gain camber in bump.

Good luck.

Look at the wheels near the air valve. There should be a part number raised on the metal surface if they were original Porsche OEM wheels. That will give you/us the size of the wheel and critically the offset. Once you/we know that, then people can suggest spacers known to work.

Thanks to all for your insight. i did a little research and found the following info:

Turbo look wheels:
Front wheels are 18 x 8.5 with a 40 offset. Tire 225/40/18
Rear wheels are 18 x 10.5with a 52 offset. Tire 265/35/18

Any spacer recommendations from my 986 brothers and sisters would be much appreciated.

Your wheel measurements may be wrong. I have a 2001 with factory turbo look wheels. I'm thinking about adding some spacers too. My wheels specs are:

F = 7.5 x 18 ET 50
R = 9.0 x 18 ET 52

violametallic-S used 18mm in the front and 23mm in the rear. He said he has 7.5 and 9.0 widths but didn't confirm the offsets. Check out the pics in his link.

18 and 23 looks great when the car is lowered. I don't want to lower my car so maybe 7mm and 15mm might be ok.

Thanks 13m Remeasured wheels this morning. Correct specs are

Turbo look wheels:
Front wheels are 18 x 8.5 with a 40 offset. Tire 225/40/18
Rear wheels are 18 x 10 with a 47 offset. Tire 265/35/18
