Magneride is actually identical from what I can tell. You should honestly get it retuned if you plan to track anyways. Non-HP cars are really the best value unless you're keeping the car completely stock. And even then in '22 I converted mine for less than the HP option cost. I think in...

Only the silver cars were automatics. One of the silver cars had a lot of transmission issues during our class and had to be taken out.

Agreed. Clean cars can be bought for under that price. The invoice price for these 600A HP cars was only 6-8k above their asking price (remember they are ‘21’s). I’m not afraid of a maintained track car but these are overpriced. When I did the Track Attack myself and only one other...

Personally I think it’s a bad deal unless it’s worth it to the buyer to own a track attack car. The only significant upgrade is a Watson roll bar. The cars have a decent amount of track use and some have had significant damage. You can get a clean HP for that price or less. If money were no...

Same experience here, HP springs made little to no difference in my ride height-it’s within margin of error. It’s an often repeated myth-especially on the Facebook groups. I also don’t consider HP springs worth the effort, not much stiffer and still too soft. A lot of people are missing the...

This is incredibly close to the same setup I'll be running (Steeda DR springs and their comp sway bar kit with the softer rear bar) and tire size. What front and rear bar settings have you used? How do you feel about the rear spring rate?

Do you have an idea how much rake there would be? I'm considering doing fronts only and keeping my HP rear springs. Looks like my HP rears are 742#. I have Steeda camber plates up front and was debating doing front Steeda DR's and using their 1/8 or 1/4" spacer to negate the front drop.

How's the ride on bumpy roads? I have the dual rates sitting in here in a box, but recent threads and posts have me concerned about the rear being too stiff. FWIW, my wheels and tires are almost identical to yours-19x11 SVE SP2's all around.

I've considered them, but really not ready to go that hardcore. At that point I would probably go MCS coilivers. I'm also not looking forward to installing the toe link bearings, but I know they are a huge bank for the buck.

I just ordered the caliper garage kit as well. I did my own alignments on my ‘94 Camaro B4C which I auto crossed, but a solid rear axle made it much easier to do toe.

I give, what is it?

They know that the springs are different. I did not see a .4” drop on my car going from std to HP springs. That’s a fact on my car. I think I’m one of the few that’s had both on the same car. Regardless I’ll post height difference when I install my dual rate springs next month (or possibly...

I think Steeda is more than aware of the difference considering the number of Mach 1’s they have built. Now my car has had both standard and HP springs installed and I had no difference in ride height. I’m getting ready to install Steeda dual rates next month (just arrived yesterday).

Bingo! A lot of people forget to reset bushings or remove bushing bind when changing ride height.

I’ve heard the same on h-pipe Mach 1’s. In fact there’s more H-pipes than x-pipes.

“so if you have a Mach 1 HP, and you want a stiffer front above the 5% larger diameter, you need to use the front (stiffest) mounting hole.” The Steeda front bar is one of the stiffest front bars made for the S550 so driving it full stiff on the street is overkill. You don’t have to be that...

I have the steeda x-pipe and I can tell a distinct difference with each mode. Each mode is about as loud the one next to it was before. 🤷‍♂️

I don’t get what you mean all this work? It’s spoiler, splitter, fender molding, springs and a sway bar. The actual HP parts were installed in a weekend (minus the spoiler and splitter), the rest are upgrades. For instance I would’ve been dropping the rear subframe anyways to install the...

The build thread isn’t dead, I just took time to drive the car and enjoy it. I finally gave in this morning and ordered Steeda Dual Rate springs. These will be going on along with the Steeda competition front and rear sway bar kit with the adjustable softer rear bar. I should’ve installed these...

Finally gave in and ordered Steeda Dual Rate springs. These will be going on along with the Steeda competition front and rear sway bar kit with the adjustable softer rear bar. I should’ve installed these instead of HP springs. Hopefully this will fix how incredibly soft the HP suspension is...
