Can you good people recommend anyone in the N.West. http://bbs.scoobynet.co.uk/smile.gif

Mellow,

I've just replied to the same post of yours in another forum saying that Powerstation are the only people who do Bump Steer removal.

Make a day of it and have lots and lots of fun finding some good roads there and back http://bbs.scoobynet.co.uk/wink.gif http://bbs.scoobynet.co.uk/biggrin.gif

try ABP motorsport in crewe, they do what they call a fast road think it might me the same thing tho have'nt checked it out myself yet

Mellow, as Matt says, go to PowerStation. Good guys who know what they're doing.

I wouldn't have the ALK fitted at the same time. Not that I've got anything against it, but handling mods are best done one at a time. Every change you make also has an opposite counter effect and it's very easy to get confused!

But go the Cheltenham. It's a great day out!

I agree with Hoppy.
I think it's pointless going out and getting lots of handling mods done at the same time.
I did mione one at a time, and am actually considering removing my front anti-roll bar and my anti-lift kit and I am concerend that one od them is actually conflicting with the bump-steer. I'll remove one at a time and go from there.
The front arb also reduces front end grip in the wet quite considerably, and I'm not sure I like that either.

I think Andy is getting a geometry set-up and the bump-steer mod confused.
The bump-steer mod wil include a geometry set-up, but not vice-versa. http://bbs.scoobynet.co.uk/smile.gif

Mellow

If you decide against Powerstation

ABP wanted £90 + vat to change my geom

I ended up going to Demon Tweeks and it cost about £60.(well worth the trip just to have a look around the showroom)

I took my car back about a month later to have the tracking changed and the newly measured settings came out almost exactly the same as before so their system is very accurate.

Hoppy 10 May 2001 03:22 AM

Andy, Hi M8! Are you saying that Demon Tweaks have the same kit as PowerStation (I was told it cost £30k!!!) at their Wrexham HQ? Do they know what bump-steer is on a Scoob and can they adjust it? For sixty quid?!

If so, that's just great. And I have to agree, their showroom is Aladin's bloody Cave! Best check my credit card status before heading over there!

Richard.

http://bbs.scoobynet.co.uk/smile.gif I don't go Demon Tweeks anymore, becuase I walk in there for something trivial and end up walking out with enough kit to run a rally team for a year.

Oh, and then the missus beats me up, not good http://bbs.scoobynet.co.uk/wink.gif

However, not sure if Tweeks do the bump steer mod. but I'm sure their kit is very good for geometry checks.

Cheers

Ian

Oops!I didn't read the thread properly http://bbs.scoobynet.co.uk/biggrin.gif

I meant if Powerstation(for the full geom + bumpsteer removal) was too far then Demon Tweeks can sort just the geometry for you(without bumpsteer correction)

The geom alone made a worthwhile improvement on my car so you maybe happy with just that

Sorry for the confusion.

PS I don't see why any normal alignment system can't be used to measure the bumpsteer.All you need to do is measure the front toe setting with the car at normal ride height, then lift the front of the car a bit and measured the toe again.The difference between the two setting would show the severity of the bumpsteer.

This does not need any special equipment.
It would then be a case of shimming the rack untill there was little or no difference in toe settings between the two heights.

The owners of kit cars and single seaters do this between meetings using simple toe gauges.
I think the only specialist part involved in bumpsteer removal is the making and safe fitting of the shims.

They pull the car down to compress the suspension, typically by hanging off the two u-shaped metal bars by the sump guard! http://bbs.scoobynet.co.uk/wink.gif

hi stef
i think the ALK works really well with bumpsteer removal. i have had to remove the ALK after a little accident in the snow and i could feel the difference on the track. the car just was not as sharp as before. now the ALK is back on and the car feels as sharp as before again. and it is not a psychological feeling either you can actually feel the ALK working. according the boys at PS subarus can't have enough caster and that what the ALK provide.

i hope this helps

Stef 13 May 2001 01:30 PM

Hi Sam.
You could be right. The problems I am encountering on track may well be caused by the fact that I am still using the original shocks on CK1, which have now covered 84,000 miles http://bbs.scoobynet.co.uk/eek.gif (probably nearer 500,000 worth of actual use though! http://bbs.scoobynet.co.uk/wink.gif )!!!!!
I have described my problem to a few people and worn dampers could well be the cause. They aren't leaking, but I guess they've had enough now. Looks like CK1 will soon be wearing new suspension (hint, hint, you know who you are. http://bbs.scoobynet.co.uk/wink.gif )
Unfortunately, funds are currently being directed at more pressing matters on the car. http://bbs.scoobynet.co.uk/wink.gif

Stef.
