LOL, I'd actually seriously put the "Sport" decal on the side just because it is a conversion that you will have done on a UL.
Good luck on this Jeff, sounds like you are underway.

can you please post the parts and part #'s. Are you converting everything with oem stuff or will you be using aftermarket springs/shocks? Just to ask a newbie question on this topic? What all has to be converted on an UL to make the spring/shock combo work? Also on the regular LS, and sport LS, are just the shocks diff? Or is it both the shock and spring? Thanks A lot

Thanks J. Let's get together once I get everything done to show off my car to you I'll bring the buffer to address any concerns you have on your black paint

I will post the complete list once I get everything, I don't have all the part #s right now.
I am using OEM sport shocks and aftermarket Tanabe NF210 lowering springs.
Nothing needs to be done really, all mechanical parts are interchangable, everything bolt up to the same location using the same hardwares. The biggest question to me before was how to disable the air suspension computer to avoid an error message showing up on the dash. The answer is, just pull the fuse on the air compressor to disable that, and no warning message is a result of that.
The OEM sport suspension consist of:
Firmer shocks
Stiffer springs
Bigger rear sway bars with bigger bushings
Firmer bushings on the upper A-arms front and rear

The issue I am facing now, is how to remove the C-pillars interior panel, they are mounted so well, it is hard to pull off, and I don't want to break anything. You have to remove these panels and the rear shelf in order to get to the strut top's nuts. I am gonna seek professional help on how to remove the panels.
