I lowered my 1999 prosche boxter with H&R springs, noticing that there is a 1/4" -1/2" height difference above the rear wheel arches, it may been like that before never noticed. Can the heights be adjusted individually to match or should I just leave it alone. I know with coil over suspension it is possible to adjust, not sure if I want to spend that kind of money over something that only bothers me.

 

I think the front is typically higher by maybe 1/4". It will also vary depending on how flat your surface is (and what options the car has). It's easy to have 1/4" or 1/2" of grade difference over 6 feet or whatever. +/- 1/4" is common. Porsche has a ride height spec, but I forget what the tolerance is -- something like +/- 5mm or 10mm. In other words, don't worry about it. Seems normal. If the front is too high, just put some gas in

P.S. You can adjust the stock struts maybe +/- 1/8", but I wouldn't even worry about that.

 

Thank you for your comments, adjusting the stock strut by 1/4" will do it , can most shock and strut shops do that or does it require a porche dealer or specialist.

 

I may be misunderstanding - but I took your original post to mean that there is a difference between the left and right sides. If that's the case, make sure that each spring is seated correctly in the strut assembly. I have heard that sometimes this isn't always done correctly and can result in one side being higher than the other.

 

I would not bother with this. Theoretically, any shop could do it, but most likely they will laugh at you being an **** perfectionist. If you are mechanically inclined, you can do it yourself. The deal is this. The bolt that goes through the wheel carrier fits through a tab in the strut. In that tab, there is a hole which is obviously bigger than the bolt. The hole and tab are more of a general locating device. The wheel carrier clamping the strut is what really holds it together. Anyway, there is some play where you can slide the strut up and down in the hole in the tab. I would guess 1/4" max, but that assumes the install is at completely the other end. You may get zero. So, I wouldn't bother paying someone to take things apart on the hope you will 1/4" (which is unlikely) and may get zero.

ofishbein could also be correct in that the springs may not be properly seated in their perches, etc. If you know what to look for, you can jack up each corner and make sure that the ends of the springs are properly seated in the depression in the spring perch of the strut. Also, there is a rubber "plate" on the top which could have been left out or is not seated correctly. These all assume a bad install.

Again, I would not worry about this unless you even are 100% sure your surface is level. The stuff I'm talking about is really a just a small trick/amount of adjustment more useful if you are trying to cross-weight a stock suspension.
