I had a track alignment and corner balance done on the GT3 a few weeks back. Had the car in for a track inspection. My tech discovered the "exhaust switching valve" on drivers side was bent and non functioning. $150 to replace. The bent one will cause uneven exhaust back pressure, by its failure to open.
I have noticed a back end scraping sound a couple of times going out or up drive ways.
Is my car too low? Any recommendations?
Here are some pics of the new one installed.

The car does have the Sharkwerks Bypass.

How much did you lower it?

fjpdds

Somewhere around 2.5- to 3 inches

2.5- to 3 inches Do you really know??
If the back was scraping??? What was the front spoiler end doing???

How much did they lower the car??? Why so much??? To gain camber?? there are shims for that.

Car Too LOW!!

Suggest that the car be brought back closer to stock ride height values for street useability, if that matters.

Cass will spank you in a std. Carrera no matter

Some figures:

Stock ground clearance is 3.66
Stock Vehicle height values are:
Front: 4.25 in measured from road surface to lower edge of hexagon head bolt on cross-member threaded connection to body.
Rear: 5.23 in measured from road surface to locating bore in the rear-axle side section

you need a race shop that does porsche to lower the car.
you will have bump steer issues as well when too low.

3" (75mm) impossible, there is not enough travel on the stock struts.

Don't go below 15mm from stock ride height unless you're re-indexing the bump steer and running different springs
