Powell xyz springs V1 and Hardcore bar.
John,
This Sticky is overdue, and an excellent idea. I just wanted to say hi, and comment on a couple of your excellent products.
I installed the subject springs and bar on my 08 TC Cobalt this year , and I'd say my autox times have improved (conservatively) a good .5 seconds or better. Your XYZ springs are firmer than stock but not harsh at all , and the Hardcore bar makes the rear end rotate very predictably. I'm not sure about others, but I softened the rebound on my rear Koni shocks when I installed the bar, which seems to have worked well.
My next items are better bushings and maybe the UCR. Thanks for your expertise and service John.

well maybe its just a local AutoX thing, but the one place I go to moved to a points based classing system vs the old "modification" based system. basically each mod is worth x-number of points and each class is within a certain points range. Apparently with what I have done I'm now running in Street Prepared instead of Street Modified

either way, I'm not in it to be crazy competitive. all I end up looking at are the RAW times anyways, and with being soo close to STX trim I can still compare to where I'm at with their times
If I really wanted to be competitive I wouldve left the car in stock class (thats where the cobalt really shines)

yea normally I run STX, but even now I cant do that according to the rules with having a catless downpipe and IC.. so looks like I'm in DSP regardless

We are STX as LNF equipped models. Everything else skips ST so far as I can tell and goes to DSP.
Another heads up for those wanting to run stock class.

I recently bought a set of 5mm spacers. And nothing but incredible quality and fit perfectly! Super quick shipping (got it the next day) but the shop is also only a 90 minute drive away

I recently installed both leading and trailing control arm bushings from JP. Simply put, EVERYONE should save up and get these! The car is so much more predictable in multiple ways. Steering feedback and response is night and day over stock, and straight line acceleration is improved greatly as well! Pedaling out of wheelspin is way easier, to the point I can actually use first gear again.
Awesome stuff John, keep up the great work
