Ok i'm not looking for a 'how to' on lowering the rear, i've read the guides and it seems pretty easy enough.....
Anyhow just wondering how much to lower mine by, here is a pic of the current ride height

what would be a sensible amount to lower by taking into consideration although the car will be road legal it's a track car 'project'

I'd personally drop it 1" and a bit, just to loose the gap between the tyre and the arch if its being used for a track car.

Cheers Mark, so just bring top of the tyre up to where the bodykit is? I have standard rear dampers at the minute as well do the aftermarket ones make a significant improvement?

Yeah bring the arch level or just tucking the tyre slightly, that'll look better but then not be too low or to harsh on the suspension.
wow.. lower it alot. :laugh:

I know you should see the front its like the R5 off road edition
50 to 60mm in my opinion. 35mm just isn't enough. However, if you can afford them, or get a good price on 2nd hand units, id put coilovers on the front. Mines prob about 80 to 90 at the front and back, i have problems with speed bumps and the sidey.
50-60 would be just right. I think 5's look that little cooler with the nose down stance too, the coilovers can be used to get this just right.

yeh don't go too low mate, you'll regret it, keep it 40mm, mines too low, it doesn't handle as well and catches on every bump going, its pissing me off, I am going to raise it as soon as i've got time.

im pretty sure mine is lower than 55mm.. feels pretty good to me :) (check pics)

Like Markey Mark has said, lower it until the top of th e tyre is level or just above the arch extension. Measure that distance first as it is. It looks like it's 2.5-3.0 inches at the moment!
Then lower the front so you've got a slight nose down rake.

Thanks for all the feedback guys i'll get on it tomorrow.
J8tro I got some coilovers sat in my room ready to go on once my top mounts arrive so setting up the front should be pretty easy.
i wont say what im thinking :wasntme:

:laugh: We all know what Spooky's thinking:smokin:, :laugh:slam the fecker.
Just be careful you don't do what I seem to have done to my shorter rear Spax RSX shock:crap:
Although I am on the case with Spax:D

If you set tha back lower than 40mm than you have to shorten the rear shocks. Otherwise they will do nothing.
na slam it, none of this top of the tyre malarkey, you want the back arch level with the top of the alloy.
Spooky style is the way :)

Spooky Style is lower than that :laugh: you want to have about 2" of the alloy under the rear bodykit arch to be like spooky:smokin: and even then you will still not be as low as Spooky:coffee:
I think Spooky has 2" of wheel showing..... :wasntme:
I think people know me too well :D

how do you stop the front from crashing out? my shocks seem to be at the end of their travel and any decent sized bump causes a right racket from the front end?!?
Awesome pics love bean :smokin: :agree:
Me Andy?
I've never had an issue with the fronts crashing out. The Avos on the car at the time allowed quite a bit of adjustment beyond what is actually recommended and I was pretty impressed with how they coped :)
What have you got up front mate?
just standard shocks with coil springs but in theary it's still the same shaft length.. maybe I just need stiffer shocks at the front..? when you turn your wheel how much shaft is showing, as yours seems a lot lower than mine!

Nipped down the ironmongers today and picked up my torsion bar removal tool, I was surprised how easy they came out considering they haven't been touched in 20 odd years.
Anyhow got the car lowered, perhaps a little too much but still not enough for spooky ;)
Still got it on axle stands at the moment while I do some grinding and painting inside the arches but will have a pic tomorrow, thanks for all the input.
Awesome, glad you got them out alright :agree:

I'll see how I fair with it like that when I eventually get the car on the road and take it from there.

No doubt but if I go too much lower ill probably struggle getting up and off my driveway!
Jimmy GTT mentioned lowering the rear more than 40mm will leave the rear shocks doing nothing so is it worth getting some shorter replacement aftermarket spax/gaz dampers.

Yes worth getting shorter rear shocks after my recent spax RSX problems I would keep away from Spax rears for now. But then I am not sure how low my rear was in the end as it was low:laugh:

Was that the rear that came with the coilover kit? So I guess it was too long after lowering?

Yeah was the rear that came with the kit:cry: I think it was not short enough for the height I was at weird as the other side is perfect and intact. I still think it's actually a fault with the damper and not the ride height of the car.

Is it possible that the dampers were bottoming out due to a loss in damping force (due to lowering) resulting in it shearing the end off?

Very possibly but I didn't think my rear was that low there is still a fair bit of movement still in the rear damper piston rod

i use clio 16v shocks.. and its as low as the pic above.. no probs.. :)

Are they the same length as the R5 GTT ones?
to low an a sidey do not go together tho..
:crap:,mines a compromise..just right i think.
:)

not sure you know.. all i know is ive had a few different rear shocks. The ones before this i had Avo's on.. and they always used to have a funny knocking/rattling sound. So switched em to clio 16v shock which i had before.. and all is good :)
