Whiteline RSB + Liftoff Oversteer

[Timbo]

With respect, Guy, I think care needs to be exercised as to whether those incidents were attributable to the fitment (or not) of a Whiteline RSB to those cars, as that is the implication of your post above. And that is the specific topic of tis thread and poll.

There are corporate reputations involved here, as I'm sure you'll appreciate

Here is Al walkers quick demonstration of lift off oversteer in an R32:

(and yes, it happens that quick)

Whilst I know Al is rather experienced in that kind event, it seems he was perhaps a bit quicker then he should have been.

And the rear was too stiff for this type of circuit.

Timbo, I'm on your side, but you must admit there is a hell of a difference between saying car X is good at Wakefield while car X may oversteer on a windy mountain road with a different surface & no room to cross the double white lines?

Guy, does power/torque have anything to do with experiencing it?

ie: would a car with lots of power experience snap oversteer more easily than the same car without the mods?

Not really Sam, its more how & when you apply it (like at the wrong time) - remember trying to drive that MR2 with bald tyres around the skidpan? - zero power & multiple spins (and that was trying to get it onto the skidpan )

I didn't get to drive it, they retired it cos of the metal showing through the rubber problem before it got round to me. Let's just say I would have been able to handle it - no-one can prove otherwise for the moment

I'm not saying that. What I am trying to address is the general contention which seems always to be sourced back to comments by Lams and you, that fitting a Whiteline RSB to a Polo GTI will lead to unintended snap oversteer. IMO, there's no evidence to support the contention, which maligns -- generally -- the beneficial effects of fitting of RSBs to Polo GTIs, and specifically, Whiteline.

In my opinion, based on extensive evidence driving on both road and track, and backed up by the experience of MACCAA and others, fitting a Whiteline RSB to the Polo GTI will reduce the more extreme understeer characteristics of the stock car without giving rise to any increased risk of unintended snap oversteer during normal or even 'spirited' road use. The exception to this (as illustrated by the Al Walker video) is where the driver makes radical changes in direction at speed and unbalances the car...the consequences of which can hardly be pinned back to the RSB!

I love these new smilies

We didn't just try it at Wakefield,Guy.Also at Eastern Creek and Winton.I think between the three tracks we covered just about every type of corner!
I did my level best to provoke it,braking into corners and backing off but to no avail.Actually,I was suprised just how benign it was!
You're too kind mentioning my 10 years track experience.....but it's more like 30.......
I think that if you're inducing this type of handling on public roads,you seriously need to slow down.Come along to a track day and do it safely.

MACCAA and I are currently searching far and wide for suppliers of RSBs for Zimmer frames
