this is something that I've been wanting to do for a long time, once the kyb's became available it made it more practical to do too.
with these modded struts I went as low as possible without extensive mods, & it should be more than low enough... I actually may need to bring it back up a bit, but coming back up is easy... this is a 1.75" drop... also going to mod the rear control arms to give the same 1.75" drop... I sourced shorter rear shocks to work at these lower heights, stocks will bottom for sure, they bottomed even with just H&R's uncut & the shaved mount... I moddified the upper shock mount to account for this when I did the H&R's... now I sourced shorter air shocks for the rear, most likely I will raise the front back about 1/2" by using uncut H&R's, & then use the rear air shocks to bring the back up same 1/2" or so... plan on eventually adding a level ride system, so even though I'm very low, my ride height will always remain the same through the level ride... load the car with 4-5 people, full tank of fuel & loaded with cargo, the level ride will bring it back up to calibrated ride height, empty the car & low fuel, it'll come down still to the pre calibrated ride height, just like a cadillac or something, I'll probably rape a caddy for the height sensor, compressor & logic controls eventually...
air suspension is not for me on a street daily driver, too many headaches there, not to mention the huge compressor & tank & computer control & everything else involved with a reliable setup, I have no need to bounce up & down really, just want it at the right height... coil overs would be cool to dial in the exact height I'd want, but even if a coil over was available, it'd probably ride like a race car, don't want that... with this method I can still have the 100% reliabilty of a steel suspension, the same ride quality as a stock H&R setup, best all around solution to me...
note that I'm not doing these myself... I had my race car fabricator do them, I just haven't had the time & he owed me so I just gave it to him to do with my instructions, one of the few people I'd ever trust to work on my stuff. I did tell him that others may be interested in going this route so he made templates & jigs to be able to recreate this if anyone is interested
if anyone wants to try this themselves the hardest part is removing the brackets fromn the donor strut, not only are they welded, but they are also bonded to prevent any movement at all, any movement would result in stress cracks & not be too safe, he had his machinest cut the tube off then bore the center till the tube was gone & just the bracket remained... then I bonded the new bracket extensions before he welded them...
