Trolley jack at one end to lift it/ give a bit more ground clearance.?

Would/should give a temporary solution.

A mate of mine got his Porsche 996 lowered, fitted new wheels and exhaust, then couldn't get it onto his drive. He ended up getting it re tarmac'd!

Hope it doesn't come to that!

A quick fix would be just to throw some stone down on the sharper side where the (probably) front wheels would tread...

A shallow sump... that one looks massive!

Or is it already.. the Lowest parts on our MK are the Steel plate between the engine and bell jousing, and the very bottom last inch or two of the exhaust silencer can.

Just had most of the car apart and was suprised at the amout of witness marks underneath.. never realise it caught in so many places so often

Setting the wishbone level isn't a prerequisite for good handling.

Raise the ride height to a more usable level.

Hi Neil
I would set the chassis height to 5 inches at the front and 5.75 at the back, the front lower wishbones normally slope slightly down at ride height and the tops slightly up, on a book dimension car.
When I fitted the crossflow to my car I shortened the sump by about an inch to be level with the bottom of the bellhousing and ran at those ride heights.
Just wind it up on the adjusters, theres normally a grub screw to lock them once set so check before trying to move them.
Paul.

jack your car up before adjusting the ride height or you'll be lifting the weight of the car as well as compressing the spring.

My car has 100mm of ground clearance at the front and slightly more at the rear, between the road and the chassis rails. the sump is a bit lower.
