Air Suspension Setup
 

Hey guys,

I have a couple questions regarding air suspension setup. As we all know, 3/8" lines having higher air flow is going to be faster in raising and lowering the car than 1/4" lines. I was talking to my shop and expressed I wanted the faster lines but they recommended that for smaller cars such as ours, 1/4" lines would be better because it would allow for a smoother transition and that though 3/8" lines would be faster, it would almost be as if the car was "hopping". Can those of you running air confirm that this is the case? Or is that an exaggeration?

Secondly, what size air tank do you recommend? 2.5 gal, 4 gal, 5 gal? I know that it depends on how often you want to air in and out, but I am going for a stealth install in either the spare tire well or underneath the car where the stock muffler would go (have Tomei 60s so that space is unoccupied), so there is space consideration. I am planning on running dual compressors for quicker refill, and am wondering how many times you can air in/out on a 2.5 gal vs 4 or 5 before you have to fill up. I would raise the car to driving height upon ignition, and then when approaching the occasional speed bump or steep incline or decline, raise the car, and then lower back to driving height (which is why I want the faster action 3/8" lines). That would be the frequency of airing in and out, with the car only really being at the hard-parked lowered stance when it's literally parked.

Also, this may be a dumb question but the system would be wired to ignition so it would automatically raise to driving height (the height the alignment would be set at) when the car is cranked, correct? I do not have to manually press the button to raise it to that height every time I get in the car? And of course, it would return to the parked stance when the car shuts off.

Long post, but basically two questions—do the faster 3/8" lines make going up and down jerky or uncomfortable, and what size air tank is ideal for my setup/usage?

Thanks!
