I've just bought a some coilovers with adjustable top mounts for my P1 and next I'm looking to uprate the anti roll bars and drop links. Do I also need to fit an anti lift kit or is this not needed with the adjustable top mounts?

 

If you have good adjustable topmounts that allow you to dial in aditional caster the ALK will give you very very minimal if not no noticeable benefit.

All the ALK effectively does is add 0.5deg of caster. With a good adjustable topmount like that of the Noltec you can add up to 2 deg of caster.

Its caster that changes your dynamic camber and gives you that lovely bite when you turn in.

 

Thanks, I might leave the ALK for now then. How much is usually required?

 

Personally i like to run as much as possible. Im using the Noltec clubsports and run an additional 2 degrees over stock.

 

Frayz is dead right. I think only Noltecs give the increase in caster.

This is a sure fire way to rid the Impreza of understeer.
The Noltecs are not that much more than the Anti lift kit.

 

whiteline top mounts give you both caster and camber and can be turned round to give more caster adjustment if required. it worth fitting the alk also for a sturdier mount merry christmas geo

 

So ALK & adjustable top mounts then?

 

i would suggest both, i have this on one of my cars works great m8

 

I have the Whiteline ALK on my car, and it had the Noltecs with the original AST's. Then, only Noltecs gave you the huge increase in caster when you fitted them 'correctly'.

Geo: Are the Whitelines ok for Classic and New Age?

They look really nice from the pics I've seen recently.

 

What special about Noltecs over other adjustable top mounts? Is there any difference between the Whiteline & Perrin ALK kits?

 

Noltecs are very different in deign. They have a floating bearing platform that allows huge changes of position of the top mount bearing. The plate is clamped in place when you do the 3 suspension top mounting bolts up tight.

If you fit the Noltecs the right way round you can gain huge increases in caster angle. Many then dial-in negative camber using camber bolts.

Normal mounts tend to afford camber changes only.

The Perrin ALK has a grease nipple fitted for the bearings which is a nice feature, but both function the same.

 

I've been told that the Whitelines will fit Classic and New Age cars. The stud pattern is the same but the bolt holes in the body of the car have been rotated, or so I am told. It looks like on a Classic you can turn the mount, as Cusco kid says and use the camber adjustment to give more castor.
Paul.

 

Yep: That is the 'right' way to fit them!
You end up with a lot of neg camber too, and we used the camber bolts to remove the excess back to 3 degs neg or there abouts.
iirc we had 4.5 deg neg camber to start with...

 

Exactly how i run mine mate. You can index the Noltecs until the maximum caster angle can be had and then get the camber dialed with camber bolts.

Big caster changes will give you big gains in turn in and leave tyre wear completely unaffected. Camber is nowhere needed as much if you run good caster angles.

 

hi m8 they are for both types buddy geo
