Hi everyone, I will be doing a suspension upgrade and was gonna be going with Zeal b6 coilovers and wanted to know a couple of things, besides upgrading my front sway bar mount...

I was reading and looking at info on the Racing Beat (RB) anti roll bars and heard good and bad stuff on the front bar, the rear everyone likes...

Its a slightly putdated post but the new front RB bars that are prone to cracking under track/heavy use that supposedly used to cost 377 are they the same as the 120 now price at RX7Store.com or have the RB redesigned the bar...

Thats it for now...will ask more questions later...LOL

Does enyone here know what im talking about or had numerous hard track sessions with RB sway bars...some body...anybody...

Early spine RB fr bars (like tripoit but prettier) were prone to track cracks. New rb fronts are like oem, but solid heavy 32mm bars (like suspension techniques). Best to get tripoint front and RB tubular rear, Lots of adjustments. Let tripoint know spring rates, inteneded use, and they will suggest the 1.25" OD tubing wall thickness.

Great thanks...now has anyone taken the new Rb Front bars to the track and compared or noticed the improvement in them...As good as the Tri Point bars are they are a bit pricey for me right now, maybe in a few years...my car is a daily that i like to play with all the time and want to tighten up my suspension and the wobble...I do like to go to the track approx 3-5 times a year...so I do want a handling of a racecar, but also less vibrations and and hard dives of the suspension on crappy roads...Thanks...

I have both the RB front and rear Sway bars but haven't had them on the track, probably won't get to try them on the track for a while too

How do they feel...what was the first impression, the understeer, oversteer, steering responce and road feel?

If you plan to track the car, I would recommend just spending the extra money on the Tri-Point bars.

Well my car is still being finished up from a long period of repairing all the damage done by the previous owners as well as putting some goodies on the car, so I haven't actually tried them out yet. Will be probably breaking in the engine with the suspension thats already on the car (stock suspension with lowering springs) then I will but on the RB sway bars, koni yellows, and tein springs at some point.

Why "upgrade" the sway bars at all? The springs that come with the B6s are stiff enough that you shouldn't need to touch the sway bars. IMO, aftermarket sway bars are really only needed for people running stock springs or softer aftermarket ones.

I guess that is true in a way, but the stock swaybars will not handle as good under a high speed turn and has anyone familliar with the drifting performance of the Tri point bars I also like to drift once in a while and i know that Tri point is adjustable how does it stand up...I know that tri point is the best, but with the Pro suspension such as Zeal B6's i doubt it will make the kind of significant improvement...I do want to know how much stiffer the RB compared with both the stock/touring and R1/R2 sway bars...

Thanks guys...

Springs, struts, swaybars (and other components) all work together in their own way to "tune" the suspension. It really just depends on your needs and what you are planning to do with the car.

rynberg

Who says? Adding a stiffer front swaybar when you are already running 500-600 lb-in springs up front isn't going to make the car handle any better. It will make the car understeer more, that's about it. Grip will probably be reduced actually.

As for adding a stiffer rear bar, that's just crazy as any experienced track person will tell you. Especially given the B6's spring rate balance (with 450-550 lb-in rear springs).

I would be getting some significant track time with the B6s before buying and bolting on more parts without even knowing if they are going to actually improve anything -- and I'm pretty sure they will do exactly the opposite.

True...

But with drifting a stiffer/adjustable rear bar will help and allow for more oversteer besides a staggered wheel setup should cure that problem a little bit IMO...and i am just worried about the front bar...and dont want the understeer, but a more agressive feel of the car...as well as an even chassis, and i read that 560/10kg front and 450/8kg rear spring are awsome on our cars...i know zeal doesnt come in that setup quite, but i can alway replace the springs...

rynberg

Like I said, with the B6s, you will have virtually zero body roll -- the car will feel like a go-kart (I know, I have B6s with the "hard" spring rates currently). Stiffer does NOT necessarily equal more grip, and sometimes means LESS. There is zero reason to go with a stiffer front bar with these springs IMO, unless you are trying to balance the chassis towards understeer. You will not get more grip or control with a stiffer front bar, you will just reduce the independence of the suspension and balance the car towards understeer.

I think you are getting a bit caught up in the "blind upgrade" disease....I STRONGLY recommend that you get some serious track time with whatever coilover setup you go with before doing any other changes to the suspension. I'll think you'll discover that you really don't NEED to make any other changes....

Whatever you do, do not run a stiffer rear bar. You do NOT need one for drifting. If you can't break the tail out with 450-550 lb-in springs, you shouldn't be drifting...

LOL

Understood...I'll take your advice...for now...unless someone else comes up with the better alternative...or whatever else is on their mind...so thanks for the input, most definetly i dont want the understeer and i guess what u are saying by a "dont get a stiffer rear bar" is it will oversteer and loose the balance...and is the R1/R2 sway bars any different...in comparison with Touring...

My second question is 10kg/560lbs front 8kg/450lbs rear is that an optimal spring rate for all sporting events to fall into...agree

Thanks for all your time...
