Default high speed stability?

I am trying to piece together a suspension setup that will provide very good handling especially at higher speeds (over 130-140). So far my plans are for new koni shocks, 35mm rear sway bar, 21 mm front sway bar, panhard bar, and Nitto 555rII's on all four wheels. Thanks ahead of time for any response. Peace.

My question is why would you want to set a car up for going 130-140. If you want a good handling car that is one thing but why specifically for going that fast? sounds like a disaster to me.

well, how about a torque arm control arms, relcoation brackets some subframe connectors and some lowering springs.that should make the car mroe stable and get better traction period, and the lower down you are the less air that gets up under you

LOL yeaaaah DR's aint made to handle really, ther made to hook up.. going straight
idk mang, def needs to be lowered so shocks and springs, other than that id suggest every suspension piece you can get ahold of, and get some good street tires like some F1 GSD3's after that get an aggressive alignment.....



and a big *** ricer wing

Well, that's a bit dangerous as described. Please elaborate on what the car is expected do do at these speeds...corner, brake (repeatedly?), straight-line only, etc...closed track? You will need more than just suspension to maintain those speeds regularly... better brakes, maybe oil/tranny/diff coolers.

I wouldn't worry about the PHR unless you're at least using DOT race tires. Shocks will be more important than springs, but since you'll already be in there you might as well do the springs at the same time.

First I'll recommend contacting Sam Strano as he's the only suspension guy with vendor status on this forum I'd consult with. He'll probably recommend you put the 35mm bar in the front, and the 21mm bar in the rear though...

thanks for the replys so far and I meant stability up to those speeds and it still feel like you are in complete control.

Get those Koni shocks for sure, also (although costly) replace what you can with lighter parts, like your wheels, brakes, control arms etc.

IT depends on what your doing with the car. If your where its legal to go that fast such as europe...the shocks and bars will make it ride pretty good at them speeds.

Wow, this has been interesting....

Some suggestions have merit, some don't, and some have nuggets of good information. Let me see if I can help a little bit. Please not this is not a solid "for sure" recommendation, I don't do that online, I want to speak to people in person....

What parts you need depends on what the car is actually doing. This is not a completely simple thing to answer, which is why we talk. I can ask questions, and you answer them honestly and we figure out what's best. 99.49% of the time (at least) the biggest issues stem from a lack of shock damping on rebound and being overly stiff on compression, both of which are huge problems with the stock shocks.

From there we can discuss other options like springs, bars, and so on. But not until we figure out what is going on (with my help).

Before I could make any concrete recomendations, I'd have to have more info on what the goal is for the car. RR, Open Road Race, street driving(?) ect. That has a HUGE impace on which way you go with the setup.
