Uneven ride height

I bought my car used from a dealer here and after I bought it I noticed the ride height was uneven (the entire right side of the car was about 'a finger' higher). I never really thought anything of it until this week when I had my PSS10's installed. While installing them my mechanic told me there was a new sub-frame piece in the rear. And right now with both front coilovers adjusted to the same spot and both rear coilovers adjusted to the same spot the car is (surprise) one finger higher on the right side.

Any clues as to what can be going on? The panels haven't been replaced so hasn't had any body damage but I'm guessing the frame is tweaked some how, although the car drives just fine. I can adjust the coilovers to make it look even but that's only an atheistic fix and besides the point.

Sometimes corner balanced = uneven ride height.

Same expereince for me with both JIC's and PSS10s, the right side (passenger side) are always 1-1.5 finger gap higher comparing to the left side, esspecially the rear. Strange... I have lowered cars for my entire life, but on the TT, the difference is huge. I have adjusted the coilovers to balance the height. I think corner balance is the way to go to correct weight distribution.

Sometime, you have to choose between corner balance and even ride height. Just take your car to a good corner balance/alignment shop and let them educate you.

I had similar issue with my PSS9, the left rear was 1/4" higher than the right rear. We had to lower the left rear coil about 1/2" to lower the car 1/4" on that corner. It's not exactly a 1:1 ratio as to coil and ride height difference as the weight distribution within the car isn't exact. That's why people corner balance. For me, I was happy just to even the car out so I don't have to look at the uneven height. Driving wise, I cannot feel the difference before and after adjustment.

I did PSS10 and also had to have them readjusted after 1,000 miles to even out the ride height. Only the right rear ended up being about 1/4" higher. Fronts are all the way down with about a finger width fender gap. Rears are about 2/3 down also with a finger width fender gap.
