As stated what sway bars do you guys recommend?
I do hpde days mainly not a daily so a bit stiffer is fine.
Thanks in advance.

 

Check this thread out from last year, has some info on sways, might be helpful.

That you sir used the search but it brought up a ton of one offs in people build threads.

 

Yeah I agree, search function is a bit frustrating. Just happened to remember that apex1 had started that thread, your username reminded me of it!

 

So that thread had some good options.
Mentioned the racing beat bars. Racing beat seem to have nice stuff are they just not up to the task?
Seems like a fair price and should be well made.

 

The problem is there isn't a single prescription. Some folks actually remove the rear bar entirely, or downgrade to a Miata one. Really depends what you want the car to do that it's not currently doing. Sure, you could stiffen everything, but is stiffer going to be faster for your specific track/purpose? E.g. I can see going stiffer for AutoX, but keeping things independent for road course.

 

I am getting a huge amount of inside tire lift in corners, I have the raving beat shocks and springs installed which is better. The inside front tire lifts a lot.
I am glad you said something because I was under the assumption that maybe juts the front bar would be all I need rear of the car seems good and maybe just a bit loose under hard braking but that should also be helped by not lifting the front inside tire correct?
Maybe just try a front bar. I do mainly hpde days at gratten gingerman, road American and Atlanta.
keep in mind I have two of these and they are my side project cars hence why I’m not juts buying full adjustable stuff and running with it. Trying to keep these budget friendly if such a thing exists. Lol

 

So if you stiffen the front and leave the rear as is, you'll add understeer. If you stiffen the rear and leave the front alone you'll add oversteer. If you upgrade both, with a matching set of say Progress or Racing Beat bars, you might consult the manufacturer on what specifically they tuned their set for.

So which behavior do you want to accomplish? If your inside (front?) tire is lifting I'd assume you're plowing /understeering, in which case what you want to play with is actually the rear bar (or further soften the front). I also assume that this lifting is happening under throttle in corner exit? If so longitudinal weight transfer also plays into this, where the rear is squatting and lifting the front. Which brings us back to your choice of spring stiffness...

Whatever you choose, I would get an adjustable bar so you can finetune for behavior.

 

It’s doing it going into the corners hard especially a slightly off chamber corner. Once back on throttle it corners nice. In fact the handling I feel is perfect as far as over under with a slight lean to oversteer produced more by braking than throttle. A slight under steer once on throttle.
Just really trying to keep the tire planted for more grip not so much handling so maybe a balanced set of front and rear which I believe Racing beat is.

 

Thanks for the guidance. Hindsight I should have writ coil overs as I’m new to learning how to setup cars but I have been a shock tech for a long time so I could probably figure out how to make them do what I want easier

Im thinking these are the way to
go so I can adjust and play with them.
Seems the best way to go.

 

Regarding the rb sways, I got them 16 yrs ago. Paired with monotube coilovers. Stiffened the car enough. But I don't race it. Don't know if they're the same quality nowadays.
I'd agree with Loki, go for adjustable sways, hotchkis are adjustable, I think? So you're good.

 

I put Progress Tech front and back on my 2007 GT last year and I’m very happy with them.Also Tien flex z coil overs with high durometer bushings and moog greasable drop links made the car handle amazing.

 

by the pictures racing beat rear is adjustable but not front. So far racing beat are the only ones that have them in stock hotchkis are backorderd till mid summer.

 

RB are both non adjustable. Progress auto?

Edit: Just saw that the rear rb sway has two attachment points. My bad.
