Mx-5 Donor - SSC

[spud69]

Hello Mick,

I did put it in the comments but i'm going to put the adjustment on the lower wishbones now i've decided on the uppers. Tranny tunnel needs widening at the rear slightly then the front to be done.

Cheers....Andrew

Sorry andy missed that one diden't read all the posts just looked at pics mate!
I had to make new rear lower wishbones for my car the mx5 wishbones were no good. The power of the bike engine totaly destroyed the rubber bush ended up having to make heavy duty wishbones with a nylon bush.
Good luck with the design its looking well.

It's looking good Andy. However I do have 1 comment about the proposed rear camber adjuster. You say there will be 2 threaded inserts on each side of the wishbone, so if i understand it correctly you will have 4 camber adjusters for the rear of the car, 2 each side?

If so then I'm not entirely sure as to how good of an idea this would be, as it would mean that it could be quite easy to add some toe-in or toe-out to the rear wheels, meaning that you could end up in the situation of scrubbing the rear tyres, or even with the rear wheels being set at an angle so that the car will have a tendency to turn around the rear wheels even when trying to drive in a straight line.

I'd say it's the other way around: you have an easy way to zero the toe on the rear.

As you are most likely aware there are quite a few Mx-5 builds in the states on the LocostUSA site. Check out Scotts 1999 Miata on the completed builds section . He machined neat brackets that use the stock eccentrics for the rear camber and toe adjustment. His car ultilizes stock a-arms but i am using the same setup with Haynes a-arms on my Miata based build that is still in the design stage.

Cheers Mick,

Yes i'm not too keen on the rubber bushes either.

The rear lower arm adjusters will be 2 on each arm Tatey, you will have to screw them in and at in unison. But as Alga says you will be able to make small amounts of toe adjustment with them. I also plan to have the same setup on the front lower wishbones to allow castor adjustment to front uprights.

Thanks ffoyd, found the LocostUSA site but cannot find a link to Scotts page if you have one.

Many Thanks.....Andrew

Here is a link to Scott's 1999 Miata build .The adusters allow for 10mm of toe or camber change. I might still use use the Haynes setup on the upper a-arm for major camber changes.
