My rear suspension seems to be quite high at the back, about four inches from top of the tyre to wheel arch (in the middle) some other owners pictures show quite high clearance but none seem as high as mine.
I dont remember it being this high either but I have just had the wheels refurbed and now it stands out a bit more, I have driven the car since refitting the tyres and it has got adjustable shocks at the rear (not sure of the make) but surely its just the springs that govern ride height?
Any suggestions other than replace springs/shocks?

Some shock absorbers such as Nitron have adjustable spring platform so the ride height can be adjusted using a 'C' spanner. The rear should be around 10mm higher than the front and measured from the outriggers not the bodywork.

Even the stock orginal shocks had adjustable spring seats though it was usually via clip/groove location choice, sometimes they have threaded collars fitted as well(if your lucky). If its just clip and groove you have to remove the shock, compress the spring and shift the clip to a lower groove. Whilst in theory it may be possible to compress spring with shock on car I doubt that the clearances will allow for spring compressors to fit. Note if not familiar with Car springs/spring compressors and forces involved get some one who knows how or you may be taking a quick trip to casualty.

Thank you for your speedy responses, I shall take the wheels off tomorrow and have a better look at the set-up.
I shall report back tomorrow with my findings.

One thing you might want to consider when adjusting ride heights is that you will alter the suspension geometry, then further suspension adjustments will be necessary for the correct set up.

If the geometry isn't set up correctly it could effect the handling and uneven tyre wear.

Well I must have done something wrong!
That was an easy job, jacked the rear of the car up with both rear wheels in the air, there were 2 locking big/thin nuts (what u guys said was a c spanner nut) and teeth on them, a gentle bit of hammer and screwdriver and around the y went no worries.
Realized before I started that I needed to slacken them off not tighten them and measured the 1st nut to its top travel and then set the second to the 1st on both sides.
No need for the wheels off let alone the suspension, all done in an hour.

Will need to book it in to have a 'four wheel alignment' but very pleased with the results, and maybe psychological but a much nicer ride with the extra suspension travel and a tweak of the gas adjustable shocks (10 turns to the right!)

Thanks for all your speedy advice and onto the next project.

I'm not sure technically on this but......
I have the spring height/tension set by the shock absorber adjustments to 2 full turns from the top travel, this was adjusted just trial and error to get the best ride height, I then again by trial and error set the shocks to 10 clicks from the minimum to give the best feel to it, I'm sorry this isn't technical but it gives me the ride height that I wanted and the best 'feel' the the car when driving.
