Weird Alignment Changes? (Page 4/4)

How do you have the shock part of the coilovers attached to the LCA?



It's really more "coilovers" on the front. Shock is in the stock spot and you cut out the entire bumpstop to put in a spring with a height adjuster

Rodney's aren't adjustable, at least not for my 86 so he says..

Think we'll see the sway bars in July?

Everything said here points to the same thing. Pre 88 Fieros's can be track cars if the suspension travel is dramatically limited. That's because they don't have ("good") suspension geometry. It wasn't intended to be competitive with the "sports car market". As I said earlier, built it like a giant go kart for autocross. But on a road course where suspension travel is important, one needs to start with an 88 chassis, if one wants to be seriously competitive. The 86 can be a starting point but requires a lot of mods and will still be compromised. Bolt on's can only go so far.

I still say, go for it. Really understand what's happening and modify what's not correct for your purpose. It's basic geometry, not rocket science. Surprise everybody.

The engineer / scientist in me automatically looks for data before making any decisions. Yellow is an 88 for that reason.

You're right, they aren't. I don't know why I thought they were

For what its worth, after waiting for a couple of months for them to be shown "in stock", I just decided to put myself on the waiting list and ordered a front swaybar from The Fiero Store. To my surprise, it was shipped and delivered a few days later.

Also FWIW, I calculate The Fiero Store front swaybar (1" dia) to be about a 400 lb/in. I calculate a rear bar (7/8") to be about 200 lb/in.

With Suspension Technologies lowering springs (of unknown stiffness) that came with the car, I cannot discern bumpsteer. The car stays relatively flat in corners, but I have not yet taken it to the track; only autocross.

reviving this for a second, but after my last event... the alignment didn't change. So. I don't understand. This car just makes up rules or something, I'm just along for the ride

Hi

Maybe the poly bushings just distorted to their limit and might stay that way for a while. I don't know, never tried them.

I kinda hope that's the case, my camber and caster are all still good so I'm gonna just say it's good and pretend I'm not worried about it

Because you can easily measure it, you have an advantage. You'll find out if poly bushings stabilize over time.
