HI all,

 

Got myself a set of mambas 12" and obviously they stick out quite a bit with the -7 offset.I was aware that I would have to cut the body so they do not rub, and have done.

But they still rub when there is some bouncing when turning hard - NOT at speed.

 

I was wondering if anybody has a photo of how far the body needed to be cut to stop rubbing completey - I am running quite low but nowhere near what I have seen in photos of other minis with wide wheels on.

 

When i jack up the front end the trumpets JUST remain in place without falling out of the top locater.

 

Obviously I could go higher but I basically dont want to.

 

Any help - thanks Jason.

 

I can add photo later of how far I have cut so far.

front trumpets will not fall out as top arm will be on bump stop, this also limits how low you can go. Also make sure you are not running on bump stops when car sat normally. also ensure dampers are not bottoming out if very low, not as easy as banging some high lows on and away you go. re. cutting out front wing usually go though original mounting hole for front arch and have clearance, also reform front arch lip to keep strength in the wing

Also depends on the type of wheel arch extensions fitted.

Minispares do templates below to download for the Sportspack arches.

Rubbing where?  
 

cut more or look at rack travel reduction kit.

if you jack the car up and your trumpets are going to fall out you have the wrong shocks fitted.

I have the kayaba gas a just all round with the mini spares C-AJJ3359 shock brackets for lowered suspension.

It is rubbing right at the front of the wheel when on tightish turning in.

 

I will add photot tonight to show how much has been removed.

Also i am fitting group 2 race arches (89mm wide).

 

I dont think i am too low.

The rack reduction kit - I have never heard of this.

I know you can get a Sportspark steering rack with reduced travel - would i be able to fit this?

Fit some hose clamps under the rack boots to the rack and see if you can live with the reduced turning circle.This may be very poor advice as should only be used to test if you can live with the reduced turning.Steve..

It's the same thing really, just collars that fit on the end of the rack to reduce travel.

With my Japanese export spec. Minilite Mk 11 6"x10 alloys with deep dish ET-15 offset and fitted with Dunlop R7 165/70x10 tyres plus Wood & Pickett arches.

I had to remove the lower front part of the wing / wheel arch almost up to the front bumper (see photo below) to achieve full lock without rubbing.

Leave enough metal after cutting the wing to bend out / form a new flange.

They are the same. But it may do nothing to fix your issue. As it was used along with raised suspension from standard and a very big cut out on the arches.

 

again picture of how it rubs and what the max turning is.

I would say 20-30 more mm as you need to cover the wheel movement in bump.

this really old pic shows how much I needed to remove.
