> did you have to align your wheels after lifting?
Yes, it will need a front end alignment because you have to drop the coil spring to insert the spacer.
> also regarding KDSS, did you have to do anything before/ after installation of spacers?
No, the OEM spacer (and to the best of my knowledge even a 1" spacer) doesn't require any KDSS adjustment. Only BP51 + SPC UCA / new coil spring / 2" + lift would require the KDSS adjustment; which from what I read KDSS adjustment should be straight forward given a 2x4 and a hex key ... nice write up on the 200 forum somewhere which I read w/ pics from someone who went w the 2" lift.
OEM spacer is not much different from stock, honestly. The spacer itself is about 10mm thick; which ends up raising the front edge of the bumper by just a little under 1". (use trigonometry calculator online w/ LC wheel base of 112" and assume 24" front coil to front bumper end.)
Largest size tire you can have w/o a larger spacer / lift is 285/65/18 (with no rubbing). I will move to that size soon (currently @ 285/60/r18). That combo of tire size and OEM spacer would give about 1.25" additional ground clearance.... tame which is what I was after... but I really like the look of McGaskins setup.... This is what I would have put the $ towards if I had to do it all over again.....
