Post Re: Front Suspension
I need to be taught how to do this properly
I can click on the photos and see them but they don't seem to display.

1. I have put a 'bottle screw' into the top link to make the camber (and castor) easily adjustable
Right and Left threads - loosen the lock nuts and turn the centre.

2. Bought roll bar links and shortened to suit - changed from the rose joint rattle units to OEM type
I know rose joints are great for competition but not good for road car

3. Fitted 4lb helper springs - these are coil bound when in use however they stop the springs from escaping from their seats when on full droop
The spring seats were lowered by Dave Gallop to get the underside of the car very slightly lower at the front.
Before adjustment the flat floor was lifting the car with 15mm rake the wrong way.

4. MGF quick rack fitted and new joints where worn.

All looks very good. I like the adjustable top wishbone :D . Did you do that yourself?
Presumably enough metal removed so it can be shorter than it was originally to give negative camber.

The thread on the top ball joint doesn't protrude far from the nyloc - I've always worked on the rule of two clear turns left showing - I guess they were designed for a plain nut with a tab washer? Might be worth checking the tightness of those from time to time, especially as the paint below them might creep a bit.

I like the shorter drop links - any impact on movement ratio (and thus stiffness)? I note you aren't on the stiffest anyway!

Dave i agree about the nylock but the ball joints i bought have a shorter threaded section but they come with a washer with lock tabs to go under the nut to stop it moving not fitted in photo's. i see the large circular washer under the joint is not peened over to lock it in position although these may have been taken before everything was finished

The pics were during works so not finished
Yes I cut the wishbones and fitted the adjusters
Could not face shimming
Not driven since the links altered

Could you give me details of the front suspension parts interested in doing this myself.

Long threaded bar and locknuts to keep dimension of the wishbone.
Screws into backboard to further give dimension of the wishbone
Cut off part of the roll bar plate
Cut wishbone in position that can be easily accessed.
12mm left right threaded bar with nuts and locknuts
Offer up and work out the movement needed -cut out this section of wishbone
Weld nuts to wishbone
Dismantle holding framework.
----- Get camber and castor checked properly!!!!
This can adjust both so may be possible to change the self centering
Mine with Ford v6 should be on the road in the next couple of months
Just now the good summer is better outside than in the workshop
