MK11 brakes/spindles/axle carrier on mk1?

[toy-driver]

Just curious how simple it is to run 5 lug mk2 brakes and hubs on a mk1. I am sure I would need to use the mk2 spindles/axle carriers. Any body done this?

i've looked into this abit. the spindle on the mk2 is abit longer than the mk2. i have some n/a spindles if your interested

[toy-driver]

Longer? as in they would make the track wider? do they just bolt on?

I'm just looking into overhauling the entire car. I figure since I'll be replacing rotors and rebuilding calipers (and so on), I could just as easily go with newer 5 lug brakes. Also 5 lug wheels just look better and are of a wide range.

To run MK2 hubs on an MK1 you will need to relocate the chassis mounts for the suspension. I am only know of one person who has done this, and he only did the rear. Here is a quote from him (JimKing).

Well, I wouldn't say I used the MK2 rear suspension. I used the MK2T rear hub assembly and brakes. The lower control arm, front link, and strut are all MK1. The rear toe link is a hybrid MK1 / MK2 part. I also moved the mounting point of the lower control arms out about 3/8" on each side, in order for the struts to clear the chassis when the suspension is unloads. This is necessary because the arm on the MK2 hub assembly that the strut mounts to sticks further inboard (in relation to the lower ball joint) than on the MK1 hub assembly.

I think I'm the only one to ever do this, and this was only because I was planning on installing MK2 ABS also.
Really if all you want are larger rims and brakes you will have an easier time finding those than making the mods necessary to use the MK2 rear hubs. In order to use the MK2 rear hubs, you have to make two mods to the rear subframe.
#1) You have to move the Lower Control Arm (LCA) mounting point on the rear subframe OUT about 10mm. This is necessary to keep the strut body from hitting the car body when the suspension drops.
#2) You have to use the MK2 toe links, and move the inboard mounting point on the rear subframe IN at least 50mm and UP about 20mm, IIRC. You need to weld small plates onto the rear subframes in order to do this. If you do not do this, the rear bump steer will be truly horrendous. The above measurements are for an 87-89 MK1. For a 85-86 model the geometry will be much different and you are on your own.

If you just want to go to five lug pattern, it's explained here.
