Anyone who has installed both of F-Sport Sway bar set & Under Chassis Brace, could you recommend the different feeling between before and after please.

Because now my IS250 RWD had installed only F-Sport Suspension without lowered. So, I would like to know some idea with those equipment. Will your car drive better after put both equipment? Should I install or not?

 

quick answer:

I'm riding on stock suspension, but.....

The sway bars made a notable difference in handling

The chassis brace (installed a few months later), not so much, although it did stiffen the rear end up slightly.

Overall, the car definitely drives much better than stock, but I would say that the majority of it was due to the sways, which are definitely worth the price IMO. The chassis brace may not be worth the price tag.


I've written about the difference in feel in a few of my other posts.

 

So, not suggest to obtain for Chassis Membrace?

 

unless you autocross or something

 

If you want the rear to feel slightly firmer (ie-more BMW-like) and/or you can pick it up cheap then I would say go for it. Otherwise, you could probably pass on it.


But, I will say that I am VERY pleased with the way my car handles overall. But, keep in mind that tires also play a major role in handling.

 

I installed the chassis brace first and noticed a slight difference. I then installed the rear sway bar and that made a bigger difference.

 

So, for upgrade with F-Sport RWD Sway bar set & F-Sport Unser Chassis Member Brace will make the car more Oversteer or more Understeer?

 

the answer is less understeer

 

I too agree with the sway bar bang for the buck, but I also install Tokico HP (blue) shocks at all for corners, this made a really nice difference in handling too. Might want to try the Tokico's with the sway bars and have the car aligned with a slight under steer, you'll feel like the rear is planted. My next suspension tweak is to upgrade factory rubber to Michelin PS2's. Good luck.

 

Thanks for sharing!

I had order both of them and they will reach my shipping agent in US next week.
I will install them and go BRC Circuit for check their increase handing.

The previous track, I'm impressive with F-Sport Shock when comparing with The OEM but not better than Tein SuperStreet which has EDFC for control and adjust the rebound , height by driver in car.

 

I too was wondering about the chassis brace..but after just recently installing the sways...I dont think the brace can add anything else now...the sways itself makes a big difference already.

 

I see that the cornering freak is happy.

Yeah if you already got the sways then you're set. I only added the brace after getting the sways because I got a good deal on it.

 

U can install the brace first.... drive for couple weeks....
then install the sways. drive ...and drive then give us the review...

 

I'm also interested in buying both the sways and chassis brace. love to go on the twisties. . how much am I looking to spend?

 

Somewhere from $600 - 900, where you buy them and if you are doing both front and rear, and if you install them yourself.
I'd recommend springs more so over brace though, it'll be cheaper, you'll not only feel the difference but also see it.
