does anyone know where i can get this done ? been told it will make a hell of a difference on my P1

Fat Boy

Only at Powerstation in Cheltenham - not far from Swansea

Other places could do it, it's just a case of setting up the alignement kit, lifting the car, measuring the bumpsteer, fitting a set of shims to space the rack out from its mounting points, remeasuring the bumpsteer and repeating this until you find the correct shim height. IIRC, you only need a couple of different shim heights to cover most cars.

I will be taking the rack of my car soon, so I guess I will have the ideal opportunity to measure and photograph the shims, if anyone would be interested in such data. I know there are some guys over on the continent who would probably benefit from this stuff.

get up to powerstation and get it done, made a slight difference on turn in, less understeer but the best improvement was under heavy braking on my p1

@MorayMckenzie
You have here already 1 interested person. Because I live in Belgium and there is no one who could perform that bumpsteer mod here...

Creepy,

There probably is, you just don't know it. All you need is someone with accurate measuring equipment, experience and the knowledge that you have to shim the rack to drop it down.

Any competent race mechanic/garage could do this for you, you must have some of them local (ish) to you?

Promax are based in Llanelli and are superb, I used them for all/any work that needed doing on my Evo V. They prepare cars for various rallys around the country. They always have Evo's in as well as Scoob's and Cosworths give them a ring but I'm sure they will be able to help

Hi Creepy, Please drop me an email to remind me. Cheers, Moray

Moray - would be very interested in pix/measurements.

Fat Boy

Different on every car,so not much point using Moray's measurements, and equally little point unless you have excellent alignment equipment to reset the geom afterwards.

PS Matt, If you can have it done by any proficient chassis specialists, why did you drive to powerstation from London to get yours done?

mutant_matt

Fatty,

Because:

a) I know that Powerstation have experience doing this on Imprezas (so is a lot less effort than explaining what I am after from some other company (who may not actually be that much closer)) and in the past have done a good job!
b) I like going to Powerstaion (it's a good drive)
c) I have got into the habit of going to Powerstation
d) I always get good service at Powerstation and I like to offer repeat business to people that give me good service

If going to Powerstation was not convenient, then I would find someone else with the equipment and capability that was.

Fat Boy,

The shim height will differ for different cars, depending on the layout of the front suspension, however, you would probably find that a small set of shim heights would cover most cars. Obviously you need chassis alignment kit to measure the bumpsteer and setup the suspension, as I stated above. However, if you lived in Belgium, maybe a trip to a local alignment rig with a simple shim design may be more cost effective than visiting Cheltenham.

greasemonkey

Moray, would I be correct in thinking that the shims are vaguely C-shaped?

Fat Boy

Matty,
Glad to hear you endorse the excellent service that is offered by Powerstation, and who, by and large, brought this useful geometry adjustment to the attention of the general impreza owning public. However, shouldn't you take out a banner ad if you're doing this much advertising...

Moray, having lived in S Wales, I suggested to the original poster that he drive to Cheltenham as he lives in Swansea, which is all of about 1.25 hours drive away (along nice roads too, Matt), and I am now aware that Belgium isn't too convenient for Cheltenham. Thanks for helping out there, don't know what we'd do without you... Yawn.

In mentioning your measurements, I was merely emphasising that it's not something that you should do blindly using someone else's measurements as, admittedly in an extreme case, it could even make the situation worse.

MorayMackenzie

Fat Boy,

I am quite aware that PS were the first to advertise this to the public in general, I was the "guinee pig" for the bumpsteer mod and it was my car they first applied the change to.

I was taking issue with "Only at Powerstation in Cheltenham", not the "- not far from Swansea " bit.

Yawn right back at you.

Moray

mutant_matt

LOL - girls, girls. Play nice now

Fat Boy

Get a grip Moray. The first comment was aimed at Matt, whom I know very well and with whom I have a long standing banter fest, both on and off line, and when he's round my house.The clue was in the way I split the post into Matt and Moray sections.

The second comment was in response to your post and is self explanatory. You have been helpful to many people on here and to me in the past, which I appreciate, but I, for one, don't appreciate the patronising 22B.com style jibes.

Having had some alignment done on an old rally car many moons ago by, it turned out, some amateurs and almost failing to make the next bend whilst "pootling" home because they forgot to do up some nuts correctly has made me aware of the necessity of having anything to do with brakes or suspension done properly. That's where my comments were coming from, FWIW. Now I am really bored with this thread. Hope the original guy got sorted...

MorayMackenzie

Fat Boy,

I guess we got our wires crossed earlier in the thread.

My original post had mentioned that the pictures may be of use to people abroad (to help envisage whats involved), and I had replies agreeing with this. Maybe I took it in the wrong context, but I guess your post came across as "there is no point bothering with this as the measurements differ for each car", which seemed to miss the whole point. This is probably why I made the belgian example reference, and thus brought on the Yawn comment from you and so on. I guess this was probably a case of crossed wires.

Anyways, I still think that pictures of example shims and a general idea of whats involved will be of use to our friends over on the continent, which is why I volunteered them.

Thanks for the kind words, by the way.

I now see what you mean about the "profesional" alignement issue. I once had a driveshaft swapped by an outfit well known to you, and on this board, and when I got home, 50 miles away, I had to investigate why I was suddenly getting brake pad knock off. I found the hub nut on the driveshaft that had been swapped had not been refitted correctly and had consequently worked its way loose! The whole wheel, brake disk and hub assembly were loose and consequently knocking the brake pads back into the calipers. I dread to think what would have happened if I hadn't spotted this and fixed it before the wheel actually parted company with the car. This was a mistake by an outfit that is considered to be one of the more reputable and professional by many here. It's frightening, IMHO.

Cheers,

Moray

Still definitely interested in photos Moray.

Fat Boy

Group hug?

Scary stuff, mind you, I lost the back wheel and halfshaft (and various bits of bodywork) from a MK 1 escort rallycar I had before the car mentioned above. having said that the goon who fitted the halfshafts into the new rear diff etc was a right tw@ and I've vowed never to do my own rebuilds again ever since......

mutant_matt

LOL - OK, Group Hug agreed

Matt

P.S. Moray, stop waffling and post the damn pictures for our continental brothers

MorayMackenzie

Enhance your calm, Mr Mutant.

I am still waiting for a convenient time to do/attempt a rack swap... as soon as I get the chance I will take the pics and post them up. It may be a couple of months though, but it will happen.

mutant_matt

I thought you already had pics? I am as calm as a calm thing with calm bits on it on calm day, in calm town

Matt

MorayMackenzie

If I already had the pics, our continental friends would already have access to them. I won't have the pics until I get the chance to do this rack swap. I will post them up as soon as I get them.

Have a great weekend guys.
