im interested in a tt but dont like the way it sits high over the tires. is there a simple way (ie. just springs) to lower car about 1 or 1 1/2 inches for cosmetic purposes only without ruining handling? i would like to avoid cost of coilovers and would run car about 10x year on track but only at moderate track speeds.

 

If you lower the car by springs only, the change in
suspension stance will impart excessive negative
camber (ie: the wheels will tilt inward too much
at the top) and the tires won't wear well or stick
well in braking etc. The stock suspension arms do
not have adjustments to change the camber that
much.
You should get lower springs, and the GT3 adjustable
control arms, and get your installer to fabricate
the right spacer to adjust the length of the arms to
regain the desired camber.

 

Hey f
As I always say to everyone who contemplates springs only: I had H&R springs on my 01TT and found the car too low and the ride too rough!! I am much happier with the Bilstein PSS-9 adjustable coilovers on my 03TT
Also, another point is that doing springs or coilovers requires removing the whole suspension and realigning the car when done and so you will get the same (HUGE) labor bill for both!! thats why I believe its better to spread this fixed cost over a larger investment in coilovers than to just put $400 springs (the labor will be about double that )

 

Joe,
I am not sure I agree with your statement. I installed PSS-9's and did not add camber plates or adjustable length control arms. My car was set precisely to GT2 specs in terms of ride height and suspension geometry. That said, the GT2 does have additional negative camber over the stock turbo but it is still a Porsche specification. I cannot state whether the suspension geometry can be brought back to original TT spec since I had no desire to do so. I don't know if you would want to bring it to original TT spec. Since the lowered ride height of the GT2 was spec'd with certain geometry from the factory, I have to believe this was due to porsche's attention to the nuances of the lowered car, the change in control arm angle, etc. So, GT2 spec can be achieved, the questions remain, can standard TT spec be acheived and would you really want to have that anyway?

EDIT:
THis argument is valid if springs alone will drop the ride height to near GT2 spec.

 

fcar, Doing just springs for cosmetic purposes in the long run will turn into a regret with your ride quality.

 

Hi Ken. If the GT2 is lower than the tt by the 1.5" that the
poster wants, and if the GT2 has the same control arms as
the tt, then you are probably correct that the result will be
able to get the GT2's allignment. I do not know if the GT2
is that low. One reason you might want to retain the stock tt
camber spec is that the front is driven, so you want the rubber
on the road, moreso than a RWD car.

GT3 arms are designed to get you MORE negative camber, not less. If you want less you'll have to machine the base of the arms and I don't recommend that unless your alble to run a Finite Element Analysis afterwards .
