Lowering front suspension

Post by stevensani »

would like to lower the front of the car about 1 1/2 inches. Does anyone know whether this is a simple procedure or is it a long job. Any help will do. thanks

you could try lowering it a bit on the adjuster plate (10 min job) on the back of the main crossmember , or if u do want that much u will have to move the torsion bar round a spline on the lower wishbone(thnk thats what its called)

but beware i lowered my by 3" :D and it has smashed a bump stop off and damaged my inner wing make sure that your bump stops are there and in good nick

It's a simple job - the crossmember bolts are likely to be rusted solid - just move the arm on the torsion bar. Don't go more than one spline as explained above.

With all the road humps you need all the suspension travel you can get or you will be forever replacing bump stop rubbers

yes i did mine by two splines looks better (in my opinion) but it has made me need a new inner wing and bump stops

1 spline = 1 1/4" try that first and see what it looks and feels like. Echo the comment on bump stops - absolutely essential, but cut down by about 1" and reshaped to allow for the lowering. This amount of lowering should not give any problems with inner wings. Ours is a bit lower, and has been for 40 years, but never had any problem with inner wing fouling.

It's not inner wing fouling as such - it gets battered out of shape by the suspension constantly hammering the bump stops on poor roads/potholes/speed bumps. And the front lower suspension arms also batter the engine bay floor - the 'tie plates'. I would not reshape the front bump stops - but at least 1" can be safely removed from the rears!

No problem with the tie plates either. We did many years ago when the LH bump stop rubber came adrift from the mounting plate, but during the restoration 12 years ago I fitted new bump stops, shortened by 1" and re-profiled to restore the progression and all is fine. We do have uprated torsion bars (Marina van), much stiffer Koni dampers and an anti-roll bar. Even so the front does not feel over-stiff, if anything a bit soft, but very well damped - just what Colin Chapman ordered!!

Oh, and we have lots of speed bumps whichever way we come into our village, so lots of exercise for the front suspension!

Your secret lies in the uprated T bars!
