I know this has been discussed here several times and the concensus seems to be that if you go any lower from the stock settings you are sacrificing performance (unless you make the suspension to work correctly by replacing parts)

Now my question is, how much of a sacrifice are we talking about?
As much as I bought the car to have fun on the track I still like driving on the street and for better looks, I would like to lower the car about a half an inch to 3/4 inch...
The low hanging splitter is not a problem, I've done 3k miles with the car on the street and haven't scraped once. I think my M3 with full track setup/coilovers was lower than this car and I never had problems with it either. And I did drive 30k miles with it on the streets.

I'm not trying to be the fastest on the track, hell I couldn't even beat the lap times of the miata guys if I tried. So will it really make a big difference in how the car performs if I drop it half an inch??

 

It will not make a "huge" difference, but it will improve your lap times a bit. I lowered mine about 1/2 and inch. Any good Porsche shop can do it. I would do an aggresive track alignement/corner balancing while you are at it.

 

So it doesn't sacrifice performance

 

I have my gt3 set at the minimum factory ride height settings which I believe is 115mm front and 128 mm rear. The car looks great and I don't have any issues with ground clearance.

 

What do you mean with minimum? as low as the thread goes or something from the owner's manual?

How do you guys measure the height? I'm used to measuring the distance between the center of the wheel hub to the fender but those measurements you gave are clearly something different...

thanks for the input!

 

Ride height is measured from the bottom of the crossmember to the ground.
Porsche recommends a front ride height of 115-120mm.
Rear ride of 128-133mm. Going lower than this would cause some bump steer issues.

 

Thanks!

Does anyone know what the height is on a stock US spec car? (I'm too lazy to walk into the garage and measure it myself...)
Should it be within that range or can it be higher from the factory?
