Ultimate Street suspension guide

thanks for input. can't help but space out some times thinking weird theories. easier than actually doing something and disproving weird theory.

The car in hard cornering is trying to unload the inside wheels though, right? I would imagine the inside wheels don't do much, especially in the rear of these cars.

This is mostly true. Which is why the handling improves so much with negative camber. The wheel with all the weight is not only more flat in a curve, it's also pointing the car in the right direction.

The rear does a lot more than you'd think. The stock shocks and springs are too soft for aggressive driving.

And way too long. If you take 3" out of the stock shocks the car handles much better.

Mercedes did that with a concept car a few years ago but did it with the front wheels F400 carve

is there any factory or race suspension design that automatically toes one side out and the other side in depending on which direction the car is being turned? would this give more ultimate control than both sides toed in?

don't know why i said "toe" in this question. no wonder i got some weird replies. i did mean to say CAMBER. especially as it applies to the rear. in other words, if some neg camber on the left wheel helps counteract the g forces in a right hand turn, would you get ultimate handling if at the same time the right wheel took on an equivalent pos CAMBER?

Confusing to me but Im not the brightest bulb. Maybe if I saw it in a diagram it would help me. But thanks for the clarification-

[Advancedynamix]

As the beam rotates toe out turns into negative camber and negative camber turns into toe in.

[nitrofarm]

Yes, as you lower the car your toe out will become negative camber.

If you lower a car with a rear beam you get Neg Toe & Neg Camber... yes or no? Thanks-

That sounds odd William. The stock festiva settings are actually positive camber iirc. They sit at about 0 to .6 degrees I think. I have never checked an aspire though, maybe the Aspire beam has negative camber. Yes, as you lower the car your toe out will become negative camber. If your sitting close to -2 degrees then the shims should get you close to -3. I think moog offers different angle choices in those shims.

Thank you I'll look into the shims.
I can't wait to get my fronts done it already handles pretty good.

I think my aspire beam with the vw setup is either 0* -1* it's been awhile since I've had it on the rack at work.

It almost makes sense to try lighter springs in front with stock shocks. I've tried the heavier & it does Pogo and is crap. We always think heavier is better with springs,but Charlie is right. The wimpy almost non-existent dampen off the oem Rio,Festy & Aspire struts. Are not suited to stiff springs.

The reason I've settled with the 120lb 12" front springs (or 150lb for DOHC G series cars) is because the adjustment range is perfect for the VW coilovers and the spring rate rise matches the shock valving of those shocks well on a Festiva. We need to remember that a 120lb spring is only a 120lb spring when compressed 1 inch. At rest it's closer to a 100lb spring, and when compressed 6" is closer to a 200lb spring. You adjust your spring rate with preload, not by just putting a stiffer spring on the car. The reason I suggest the 150lb springs on G series equipped cars is because the engine is further forward and there is more weight on the front wheels. The 150lb springs have a faster rate rise which matches the extra load of the heavier driveline which is moved forward. Both the 120lb springs and the 150lb springs can be adjusted to 175lbs, if you need that, with the preload adjusters.

What is the factory rear camber for the festiva beam?
I just put a camber gauge on my aspire beam swapped festiva and have about 1.75 negative camber .
My rear has the vw rears with 120 springs all the way up .
I have about 16th toe out in the rear .
I guess my question is Will I be able to achieve the 3 degrees with the moog shims and when I lower the car will I gain + camber and toe?
