MG MGB Technical - Negative Camber Wishbone Arms

I am looking for help on negative camber wishbones. I've heard they increase tire wear towards the inside. My question is are they suitable for street use? Also, these castor plates that fit between the crossmember and the frame - effective or not? I will be using 15"x6" wire wheels with an all-season radial tire. Thank You, Geoff

Not tried the negative camber arms, but the castor reduction kit is excellent!

Its by far the most cost-effective change I've made to my car: the steering is lighter, turn-in is far more positive, and there's no 'weighting up' of the steering in tighter corners. It is a must if you drive along a lot of twisty roads: far less tiring.

Geoff,

I have the -ve camber wishbones fitted to my 71 B and after 10000 miles there is no discernable wear due to the change in wheel angle - my only caveat is that it isn't driven hard - sunny sundays etc only!

I have seen critiscism of some caster wedges - search the archives

Geoff,

I've used them for about 20 years. They did not suit my '78 GT, but they are excellent on my '64 MGB. The way the later cars are jacked up may have had something to do with it, or perhaps it was my choice of springs.

My driving style was wearing the outside edge of the tyres, now there is even wear.

The turn in is excellent, the inside wheel just grips and grips, so the back end must be kept soft. I run Chrome Bumper GT springs on the front with a 3/4 anti-roll bar and the wishbones have V8 bushes. The front shocka absorder have thicker fluid and the rids suits most roads.

John Turner & John Prewer, they are for my '65 roadster. I'm in the process of a complete restoration and rebuilding the car from the ground up. Haven't bought springs - mine are shot along with the basket case car I got for parts. I have 4 front springs - all of different heights and 4 rear springs of varing height and lenght? Have the V8 bushings - got them from a friend. The car was fitted with the orginal 9/16 roll bar that I have already purchased new bushings, the uprated ones (red) from Moss.
D Ainsworth - what year of car do you have these fitted? Thank You for the response, Geoff

Geoff,

I had an Audi A4 road car for a while and now have a Subaru Impreza, both have great grip turing in to corners. They seem to want to stick to a corner and can go round it at silly speeds. The negative camber wishbones help my MGB go some way towards this.

What I have done (mostly!) is to follow the original factory tuning advice as far as possible instead of using all the new mods you can get, and I think it works. Keep the rear standard and stiffen the front with GT springs and stiffer shocks.

With the live rear axle the MGB will never be as efficient at cornering as the modern cars, but it is far better than the original setup and great fun to drive.

I advise 185/70 tyres and getting a shop to grease the front suspension with an air gun which does the job far better than a hand operated grease gun, will last much longer and will make the steering lighter.

John.
