At the very least, I don't have to sit around wondering what will be pissing me off this weekend.

OK, tension links, camber links and rear control arm are all at the machine shop for bushing R&R. I don't have the equipment to do it, nor do I have the interest. It sounds like fun, but I'm farming it out. As it is, I know everything is going to be a real treat to refit, but the good news is I got this far.

The bitch is I broke the LR Magneride travel sensor, so I get to buy a new one of those if I can't cobble this one back together.

Hi everyone - I am currently considering either Koni or Steeda adjustable struts/shocks for my "very budget" CAM-C build for local occasional autocross use (2106 GT PP). Currently it is on a Steeda "lowering spring" that was on the car when I bought it, on the stock struts/shocks and bars, stock Pirelli summer tires but square 275s on 19x10 wheels, and camber bolts. The car seems to be ponderous and rolly in a way that makes it not fun when autocrossing. (Tires are of course the first thing to address to be quicker.)

I am not particularly concerned with ending up with a harsh street ride if it provides for as good an autocrossing car as I can muster on a budget, and thus I suspect I will want whichever one is better suited with whatever (stiff) spring is ultimately chosen.

Is there a consensus as to which of these would be a better starting point, or is there a third similar budget spring/strut option I am not considering? Thanks in advance.

If you're going to do it, do it right: good coilovers. You cannot get properly stiff for CAM with lowering springs and struts. You make up the lack of speed in tighter corners with high speed transitions (slaloms and high speed gates). This requires having a car that is easy to push hard and transitions quickly, leading to stiff front springs in particular.

This Megan Racing/Bilstein set up was the best bang for the buck setup I could find. I started my CAM build with konis and steeda springs but that only lasted a few months. The twin tube konis don't particularly ride well on the street. This Monotube setup was far superior in ride control and comfort. I just sold my GT and have this set available.

I wouldn't turn someone away from that megan coilover setup. That said, Konis and some good springs with decent spring rates is a perfectly fun and fast setup for a casual autocrosser in CAMC. It will be more capable than most drivers. Considering you want to reuse your current 10" square wheels, seems like a fine enough plan.

Between the Konis adjustables and the Steeda adjustables, they're made in the same factory. The differences are in the valving and the color of the paint. I don't know anyone who's run both, so flip a coin?

After spending $1300 on springs, shocks, and hopefully some camber plates, you're over half-way to the mentioned coilover package, and after paying for an install, its more like 3/4 the way there. Maybe worth spending a little bit more and getting into a better damper and coilover on the linked setup.

To compensate for inadequate spring stiffness, you might end up with a huge front swaybar on full stiff. It sort of works... but it’s another added cost to consider vs coil overs.

Which has its own issues that don't really do the same thing as the stiffer fronts (less overall grip vs more spring).

Thank you to everyone for your comments and suggestions. I do have a further question regarding not being able to get a suspension stiff enough for CAM on springs/struts. Is the problem that nobody is making a sufficiently stiff spring, or that no off-the-shelf strut is being made that can damp such a spring (or both)?

I am never going to turn this car into a nationally competitive CAM-C car. I would be happy to settle for simply "a heck of a lot better" than what I have now. What I would like is to make it more point-and-shoot like my SSC FR-S, which is on Konis, Eibach pro springs and bars, and to me feels pretty great. I understand that it may be impossible to make it exactly like it due to weight and proportions, but I would like to make it closer to that, so it is not ponderous and rolling back and forth, where it feels like my inputs take half a second to make it to the ground.

Is anyone running around on an off-the shelf strut/shock and stiff spring that they think is a really good combo?

I recognize that I might look back and say "well I should have just bought a good set of coils" but I want to explore my options. (That is a steal of a price for those proven re-valved coilovers.)

Thank you again.

The problem is that the droop length of the front struts prevent a stiffer spring. Something stiffer is too short and would fall off the perches or have a tall ride height.
