I have recently purchased the Sharkwerks front RSS sway bars and wondered what the down side was to the more aggressive front sway bar. Someone said I would have more understeer or understeer I can not remember. Also the front sways did not fit in the bushing clamps because of a larger size so I am attempting to order the GT3 front bushing to see if that helps but if it does not will clamp them down. Any thoughts on the up and downs?

 

I would get with Alex first and i am sure he will have a solution for you very quickly.
Good luck.

 

hey jnixon, you can actually use a gt3 or gt2 bushing but RSS always uses the factory one hence they don't include other bushings (H&R style ones are noisier which is why). Even though I believe it's about 1-2cm bigger the rubber bushings (factory) do stretch and fit over them just fine. I'll be at the track all day but if you call just ask for James and have the installer call us

 

I used the GT3 bushing and they worked perfectly so I would suggest to any one on this board that if you order the sway bars from RSS use the GT3 bushings.

 

If you already know, never mind. Otherwise, just trying to help here:

If you only change the front sway bar to a stiffer bar, what you will see is more understeer. The down side is that for the Turbo, in general, this is the opposite of what tuners would recommend.

Because a 4WD car like the Turbo has the tendency to neutral steer/understeer, and because pro (and amateur) racers like a little bit of oversteer in a sport car, the typical recommended setting is soft front sway, and stiff rear sway. This is why you would see some people keep the stock front sway, while changing the REAR sway to a stiffer one.
So basically for sway bar settings:
1. Soft front + stiff rear = less understeer, more oversteer,
2. Stiff front + soft rear = more understeer, less oversteer.

There is a very nice article that I posted on this thread here http://www.rennteam.com/forum/thread...html#p20093313
that goes into details about slip angle, understeer/oversteer.
For example, any change that reduces the front slip angle would also reduce understeer. This is why the Techart Turbo in the recent Tuner GP in Europe has wider FRONT (reduces understeer); another example of tuners wanting to reduce understeer in the Turbo.

 

The way sways work is the stiffer you make one end of the car (relative to the other end), the more grip the opposite end will have. So stiffening the front will give more grip on the rear and visa-versa. So if you want less understeer (ie. more grip on the front) then you stiffen the rear sways...
