Lift kit?

[Steve_D]

Has anybody used or investigated a suspension lift kit either hydraulic or pneumatic?
I'm thinking of the type that sits on the existing coilover spring seat with the spring above it.

Looking for ideas for another car we are working on.

Many thanks

Hi Steve

SS fitted one on the black monster Martin now has, Nitron shocks i think 40mm lift. PM me for another contact you already have.

works ok... installation is key along with a mod to bleed the air out the system

Found this.

looks like a bit of a compromise to me, they do a 64mm lift kit but you would need to lose 80mm of spring to fit it, for the smaller kit its a 64mm loss of spring (a bit less if your pre load is wound up a lot)for 32mm of lift, but is that enough to bother with anyway @ £1127(todays rate)+ shipping + VAT and Import Duty?

ETS the kit above looks a little more "polished" and TUV approval is a good thing.

Michael,

The KW system looks the business what is the added weight to install this thing
I am curious and the only way to go in my view is the all car system 4 wheels

There is prob enough thread left on my coil overs to do it without shortening the spring. Or am I not understanding it correctly? Also the 45 mm lift will translate to more actual height depending on the mech advantage of the wishbones will it not?

If your car is set up as recommended then you will have approx. 6" under the chassis at the back so you only need these at the front.
40mm of lift at the front should be plenty to clear sleeping policemen.

If you have dropped your ride height much below the factory recommended height then for road use you will bottom out on uneven country roads. Not a problem on track.

Speed humps and steep drives are the only reason to go this (expensive) route IMO.

Thanks for the input so far guys.
Just checked my GTR and I would need to put shorter springs on even though my car is already set slightly higher than Factory spec due to the angle on my drive.

Will check the spring seat height on one of the cars these are destined for in the morning.

Just had a look into the KW Kit. Price quoted £3475.40 from USA (only place I could find a price).
At that price the Ramlift at one third of the price is a snip!
At the end of the day these things are only meant to be used at parking speeds, I reckon the Ramlift would do the job. personally I have a couple of plastic chocks in the luggage bin for when I get caught out on a steep ramp.

Just another thought these things will only work if you have enough "sag" in your suspension already, ie if you have 25 mm sag a 40 mm ram will only raise the car by 25mm the rest will be spring compression.

I remebered and found this video. It goes up and down both front and back : http://www.youtube.com/watch?v=eZMIRULIkXU&fea...
I believe it was someone in the USA on this forum from time to time, who modified heavily the standard GTR during his build. Can't remember the name but I think he was in the medical field

Just rememeber most racers dont like to much droop, and most of the time they tend to limit it, so If you want more than 40mm lift then you end up with a bigger droop figure.

I don't want to spoil the fun.
I had this kit on a few of my cars.
And it leaked after a short while.
On the other hand it is easy to refill.

Steven,

KW´s site says 6 kg for both systems (HLS2-front, HLS4-front and rear).
That can not be correct. I assume this weight is for the HLS2.

The cylinders need 65 mm thread left at the damper.
At my car there is no thread left at the front using the standard springs and helper springs.
I would need shorter springs to use these lifts.

was a guy on locost builder site who made his own kit & sold them, will dig about and see if i find the link, was also selling on e bay at the time

just watched some of his other videos... you need suspension like this to copy his car!!!!

Fascinating. That looks like the way to do it if you want a no compromise lift kit.
