I am thinking about lowering my car with kyb shocks and tein springs. I know that it only lowers our cars about a inch all the way around. I have a friend that works at a tire shop. He said that they often have problems getting lowered cars up on the rack for an alignment. Has anybody with the tein springs had this problem?

NO! You wont have any problems whatsoever

There have been some cases where the shops can't align the car because of any aftermarket modifications to your car.

For example, I have the SSIII front and and rear splitters and some shops couldn't get my car on their lift because they were afraid of damaging my front.
Some can do it, they just don't want to take the risk of damaging your car.

Luckly I have a friend who owns a shop where a majority of their customers have modified cars and it's not a problem for them to get any car on their lift, hoist, etc.

Sears took mine in with tein springs no problem >> Same with tire discounters. Its not that low if you have stock body.
