thanks dom,
I have looked into this long and hard, It would seem there's no real way to do this cheaply (even DIY) and from what I understand of the two currently available commercially, one is prone to leakage; this is obviously not even a starter, you wouldn't want hydraulic fluid over your brake discs etc. Which leaves KW.

There is also Ram-Lift, not sure if that is the product that is "prone to leak" as mentioned in the last post. As I understand, they are using newer pumps that are faster and I have not heard of anyone having leaking problems. It will also give more lift than the KW option, providing there is enough droop available in the shocks.

From RCR in US-- Made for there Superlite cars but will work in a Ultima


•Electric/Hydraulic lift kit for one axle (front or rear). Lifts the front or rear of the car about 3” for improved clearance over speed bumps, on steep driveways, etc. Invaluable to protect your splitter and front end from scraping. Includes pump (one pump can lift one or both ends of the car), 2 spring mounts, 2 lift units, remote reservoir, appropriate lines to pump, switch, and flex lines to lift units from pump. The standard ISIS electrical system is pre-configured for this kit, so wiring it is plug-and-play. Once the first lift unit has been purchased, the other end can be plumbed in using the same pump, and at a lower cost than the alternative of having to buy two separate lift systems. You will need to source shorter springs when using this lift kit, and some machining may be needed on the shock collar. Call Superlite Cars for details.

bks....

The company that makes them are
http://www.ramliftpro.com/contact.html

The pump used is a marine autopilot steering pump such as a raymarine T1 although accu-steer or any other suitable brand with the correct rating can be used. Without the marine autopilot electronics it's just a reverse hydraulic pump using a crossover switch to reverse the polarity.
The original T1 pump has a no load flow rate of 1.0cu In per sec flow rate that lifts the 2.5" platforms in about 10 secs. If I was bothered and wanted it quicker, next time I would have a look at this

http://www.ebay.co.uk/itm/Autopilot-Hydraulic-Pump...

Which would maybe half the lift time but it looks bigger and heavier.

If you have manufacturing capability you can knock your own platforms up to suit your own specific requirements and save a fair amount of money. While mine are dismantled I can send pics or drawings just email me.

And why on earth would they be prone to leaking...? Unless of course the US use the UK as the scrap bin to offload the reject parts...haha

Does the fitting of these lifters have any adverse effect on the handling or stability when in the 'rest' position i.e. normal driving ?

With the kit you actually feel more comfortable in running a slighty lower ride height as you have the knowledge that the lift will get you out of trouble.
You will need to play with new spring lengths and ratings as you loose for instance approx 3" of your current spring length.

No point in racing or tracking with them but for the road they are a god send.

Pump..?...fittings..?...platforms...?... Gravity feed reservoir..?

If I had leaks in my brake system
I wouldn't generalise and say brake systems are prone to leaks....???!

I've used mine now since 2010 without issue..

The pump for the Ram-lift kit has been changed. Apparently it works in less than half the time than the old one. Going off what others who have installed it and comparing their time to my time. I'm thinking of upgrading the pump myself but too much other crap to do.

Unless you've come across some unusually large speed humps, I'm not sure if you're trying to fix a problem that doesn't exist?

Even running the front splitter, I didn't manage to ground out the GTR on any speed humps, nor ferry ramps come to that?

Are you running lower suspension than 'stock'?

hi stig.

factory built car running factory height.

but im in Cheshire. land of the bad roads and stupid speed humps and steep ramps into petrol stations.

unfortunately the ride height isnt the problem its the overhang of the front standard option splitter.

sometime an inch extra would be more than enough, which is why ive also been looking at a single ramp pushing against my anti roll bar just to raise a bit

Not sure what model pump he now ships. I have the old pump.

Stig, as Dom mentioned, it is the overhang that is the problem. This is very apparent when trying to get into steep driveways or anything with an incline you are approaching that will try to rip of your splitter. I live in San Francisco, so we do have a few of those pesky hills and inclines to deal with.

The new faster one is $650 plus around £100 with shipping and import tax so I will have a go with the Hy-prodrive PR2012 and let you know how I get on
