Apart from better traction at hard launches, can you feel an improvement of the front end's stiffness as the manufacturers claim? ie do they improve the front end's integrity under track conditions?
(no insult intended as I'm the same)
but I don't think the man has ever put his car under track conditions.....
maybe someone else can help with this question.
edit : i had this page on last night and when i replied, i didn't bother refreshing and didn't realise it had moved on
im running an avid racing traction bar on k-swaped ek and it works well on hard launches and seems fine in the twisties had to modify the splash tray under the front of the engine bay to fit though
Does anyone get any rattleing from their traction bars?
Don't have 'traction bars', but I used to own a 'Clubman' style sports car (similar to a Lotus 7) that used spherical rod ends in the suspension (aka 'Rose joints'). There are two basic kinds of these rod ends that are used in suspension applications, where the sphere is held in a steel or bronze cage (metal to metal), or where there is a teflon liner between the sphere and cage. Both kinds will rattle once any wear has occurred between the sphere and the cage or teflon liner.
It's not really an issue unless the wear becomes excessive, though once a clearance exists dirt more easily gets into the joint and wear accelerates very quickly. The teflon lined ones are better because the tight fitting teflon liner 'self wipes' the dirt from the sphere before it gets in, but not forever. Also the teflon lined rod ends require no lubrication as do the metal to metal rod ends (i.e. the metal to metal rod ends need grease or oil), and grease or oil attracts dirt and turns into grinding paste...
There are also cheaper rod ends that have a nylon liner, but these are not very suitable because the liner pounds out in high load applications.

They should do, because they will provide more stable geometry, i.e. since the longitudinal location of the wheel is stabilised the caster angle will remain the same under brakes or hard aceleration. This may have direct benefits for grip, but a lot of the benefit will be in the form of more consistant driver feedback. It removes a source of 'non-linearity', which is nearly always a good thing.
Unstable longitudinal wheel location causes force to 'wind up' in the suspension linkages controlling longitudinal location (i.e. metal flexure) and any associated rubber bushes. Once this 'wind up' reaches a point that the force that is 'stored' in the flexing component becomes more than the tyre's capacity to grip, then the force (added to tractive forces created by the brakes or acceleration) will cause the tyre to lose grip as the tension is released (i.e. losing grip will cause tension to be released, and tension can cause loss of grip, a chicken and egg thing...).
Preventing the 'wind up' (i.e. eliminating flexure) means no forces get 'stored' in the suspension components, and the tyres only have to deal with rotational forces created by the brakes or engine.
I'll be installing the inno replacement x-member/traction bar on my ED9 as a way to rid of the horrid factory x-member. Still unsure if I would install a traction bar setup in my eg and dc2 down the track, as I have reservations about chopping up the splash shield to clear the traction bar and also the additional bar and attachment plate that mounts onto the LCA adds unsprung weight.
ok we have proof these are for the 1/4 mile , what about track tho ? anyone experienced for track work ?
A thought would be this doesn't allow enough frontal suspension movement to be beneficial for track work.
We used it with and without on our egk20a
A pro driver who drove our car said it made some differences.
In my opinion they cover up the inherent deficincies in engine swaps where driveshaft angles get mucked up by the placement of the engine in the engine bay. If you set your suspension up properly I believe you do not get any benefit from them.
