Lately I've noticed that my car sits front end high. I measured from the ground to the fender arch 26.0 rear 26.75+ front. Ideally the car would be level and maybe a touch lower. I don't race or track. Is there a reasonably priced option to accomplish this? I've heard lowering these cars even a small amount tears up tires. Lowering spring kits all say -1inch front and rear. Based on this starting point the front needs to come down more.

BTW -- 01 996tt, stock wheels and tire sizes.. I do plan to move to 19's with the 315/25-19 and 225/35-19 combo relatively soon. (maybe at the same time)

 

Also, all suspension is stock..

 

Invest in some lowering springs, they're relatively inexpensive and a good temporary measure until some coilovers or additional new springs. This should even it out. Also, why 225/35/19 when you go to 19 inch wheels? Why not 235?

 

If I just do the lowing springs will it chew up tires? Will it bottom out on speed bumps? Will the back wheels sit vertically or will they lean in at the top?

I've heard the 225's are actually closer to stock than 235's... No?

 

Just to provide a bit of additional confirmation about what you're seeing, I went out to the garage and measured my own 2001 996TT which is also riding on stock sized tires. I got 26.5 inches in front and 26 inches in the rear, for reference on my stock suspension.

I never really noticed the front riding high, but obviously it is a bit higher than the rear. I just bought a set of H&R lowering springs and am eager to see how that changes the overall balance between the front and rear, if at all.

 

I previously had Champion lowering springs and thought they were worn out or sagging as my rear was lower than the front, so I ordered coilovers.

When requesting measurements from other members in an attempt to set my ride height. It appears that measuring to the fender well/lip yields a higher front number even if the car is completely level. F1crazydriver advised me that his car was level yet his front measurement is larger than the rear.

Try measuring to the proper points, as recommended by Porsche as this misconception cost me $$$$ for the coil overs and alignment only to find out this is normal.

Hope this helps and good luck and thanks to all the members here who helped me figure this out.

 

Well I got the springs put on back in September, and my tires have been holding up just fine. The car does not bottom out ever on speed bumps, don't worry about that. And the back wheels do have a very slight negative camber, so they do lean in a hair at the top. Looks very aggressive in my opinion though.

With the tire sizes, I don't necessarily see the best fitment the one that's "closest" to stock. Instead, I worried about the front to rear rolling diameter ratio. If the 225 provides for a good ratio though, then it's no problem! Just make sure it fits the width of those wide 8-9 inch aftermarket wheels for the front!

 

I run 245/40/18 fronts on stock rims and my height is 26.75"
I also run 295/35/18 rears on stock rims and height is just under 26.9"

 

Very helpful to know that, thanks! It would explain why so many of us get the measurements that we do.

 

The H&R OE Sport Springs lower your car 1" inch in the front and rear. OE Sport Springs offer a mild lowering to cleanup that "too high-rally-stock look." Stock ride comfort is retained. You shouldn't have a problem bottoming out unless the speed bumps are massive. Springs shouldn't tear tires up unless your alignment is out. For more information Click Here.

 

HI,Why dont you just go to Tire Racks web site and look up the diameters of those size tires?

 

Johnspeed

Tire rack says 225 is the replacent when used with the 315-25..

 

I would look up the tire specs yourself ,just for piece of mind..

 

OK thx

 

You're measuring fender opening height not ride height.

Front ride height for Turbo USA (ROW) with 18" wheels is 158 +/- 10 mm (138 +/- 10 mm). This is measured from road contact surface to lower edge of hexagon-head bolt (a/f 18) of the tension strut screw.

Rear ride height for same car/same wheel size is USA (ROW) 153 +/- 10 mm (153 +/- 10 mm). This is measured from road contact surface to the locating bore in the rear axle side section (between the two and camber eccentrics).

The car should be empty of drive, passengers, junk. Tank should be full.
Spare tire/tool kit/etc should be present and properly secured.
