Whiteline Bump Steer Kit?

im not fitting mine till the bad weather has gone as the salt will wear the rose joints. I'm looking forward to trying it

Did you manage to fit those?

They're still gritting the roads where I live so not yet! Was hopin to have fitted it by now.

Has anyone independant of Whiteline measured the bumpsteer on a GTI? The amount of bumpsteer that Whiteline claim the car has is staggering, and I'd expect the car to be a pig to drive with such a massive about of bumpsteer. Having played with the bumpsteer on track cars with adjustable steering arm height, 8mm change with 40mm suspension displacement is very obvious, with on the road characteristics making the car feel very unsettled over pot holes and similar road defects that only displace one side of the car's suspension.

I wonder how Whiteline measured the bumpsteer on the golf - fit a damper with the spring removed, support the chassis, and stroke the wheel with a jack?

[mkviken]

I assumed that's how they would have measured it yeah. They must have some kind of jig as they mam all sorts of parts to alter geometry.

Ballance motorsport told me 8mm bump steer and said it was more worthwhile than Changing the ARBs as it was so bad as standard.

If it's so bad, how come no-one ever complains about it

I'm similarly cynical. Considering the geometry of the GTI is fundamentally the same as some of the softer sprung models which allow the wheel to travel much further for a given bump, you'd half expect the lesser models to veer off the road at the first sign of a bump!

8mm of toe is about 1 degree, so pretty significant.

No, 8 mm (with an 18" wheel) isn't 1°. It's just about 20 minutes.

The question is does a stock height GTI have benefits from the BSK or does a lowered GTI benefit?

arcsin(8/457.2)= ~1deg?

Have I had a very dim moment?

As for the stock height v's lowered question, without the bumpsteer curve for both rod-end heights v's ride height, I agree it's impossible to know if the kit will do anything to assist a stock or lowered vehicle.

Cos it's not someone many people know a out or investigate. How many people know about caster before the WALK came out and now everyone loves it

People fit coils overs and expect the car to handle as good as it can. It these little changes add up

The GTI has more bump steer than a TT or S3 and they feel better (apparently)

Everyone seems to rate the WALK myself included so I reckon whiteline know what they're talking about And the BSK is a cheap mod so worth a go IMO.

I'm not suggesting that Whiteline's Bump Steer isn't worthwhile but just questioning and challenging it. It's all part of assessment

Isn't the S3 geo the same as the GTI, just aluminium alloy instead of cast steel?

I did  i also know all about KPI and camber, but then i did spend 5 yrs learning my trade, now they do it in 12 months, its not right

back on topic, rose joints are commonly used on track cars to A, keep a tight feel to the steering feedback and B to pervent tramlining effects (bump steer) so basiclly there is nothing new about this kit, its used many times over on the track week in week out and has done for decades

the thing is (and this goes for any mod) once you have spent your money buying it, then maybe paying to have it fitted you will always see some benefits as you wanna justify the spend, even if the benefits are very small

....So very true!

If the bump steer is as bad on the mk5 as they would have you believe then I can see the principles and benefits of the BSK and would probably give it a try for the money tbh, sadly I can't ignore the engineer inside me which knows that the exposed rose joints and our climate mixed with 6 months of road salt are just asking for trouble...
