Put the passengers on a diet? Other than that you will be spending money with little chance of success. You could try contacting Gaz technical dept, but in my experience with them, they were worse than useless. Especially when discussing spring and damper rates for specific applications. I very much got the feeling they only sold what was on the shelf. You could try Kevin at Protech, he is a top bloke and could advise some new springs perhaps. I would still be looking down the rubber route if it was me.

Will the cones provide enough clearance with the wheels been quite large?

[Cooperman]

Of course they will. They sit inside the envelope of the rear sub-frame. The rear wheel clearance issue is usually the clearance between the radius arm and the tyre.

Whatever you do, there may well still be a problem with the tyre hitting the wheel arch on 'bump'  and the only solution might be a body modification to re-shape the basic wheel arch. This would be expensive, but modifications often do involve spending a lot of cash. However, rubber cone springs may well eliminate the problem.

Very wide wheels on a road car do tend to throw up problems.

Ensure your bump stops are correctly fitted, this should eliminate unneccesary clashing of the suspension components.

 

For set up, get the car corner weighted, this envolves putting the car on a set of scales. as you wind the coilover/hi-low up and down it applys more pressure over the ground. Even weight will allow the more even, predictable drive and better handing characteristics.

 

He is running completely non standard components?

 

Winding the coilover up or down won't make an ounce of difference to individual ground pressure (within reason) - only way to change that is to change the C of G of the car.

Umm... It does work that way...

wouldn't doing this make it worse seen as I will have to lower the rear?

[Cooperman]

The root cause of the problem is the coil springs which are not as good as the original rubber cone springs.

Answer is to re-fit the springs which were designed for the car, set the ride height to standard and then, if the wheels still rub, fit wheels which are nearer to the originals.

Then the problem will be gone forever.

No, its not really relevent in your case, any downward adjustment of the platford to even up the balance would just be detrimental to arch height, even if it is a small amount
