Hi Guys,

Has anyone heard of Quantum Racing Suspension, the are a UK company that makes suspension for race cars. I have a set of their height and rate adjustable coil-overs. These things are made of aluminum (see "Light as F%#*"), and have spring rates of 10kg/mm (see "Stiff as F%#*").

I have tried the net to little avail, only being featured in Mini Cooper racing. The latest HPI, GTR Special, has an article at the back with the "Trial" GTR have a set.

If anyone knows a seller or website could you please let me know.

See'ya:burnout:

They are manufactured for TRIAL, and TRIAL puts their brand name on them, and resells them.

There are different specs:

F8K/R6K (Street)

F10K/R8K (Circuit)

F10K/R8K (Street)

F12K/R10K (Circuit)

Excellent coilovers. They range in price from 348,000 - 425,000 for R33 GTS-t models.

Thanks for the response Maddness and Merli,

Its good to see that someone else has heard of these coilovers.

Yeah I do feel lucky as I got them pretty cheap off a friend who imports cars. I will have to attempt to get a sticker for it, like on the Trial GTR in HPI.

well so far I have contacted these people - www.shockreco.com.au - and I am awaiting a reply. I have also spoken to the guy I got them off, and he is lending me a let of shocks and getting in touch with a place in Melbourne about rebuilding it

Has yours gone a bit clunky as well? I think becasue the oil has come out, the piston is moving about a bit. Hopefully they can be repaired, as they are awesome :thumbsup:

I like how hard they are, as with 225x16 on 16x7.5 rims, it makes up for a bit of sidewall flex and makes them grip really well

Yeah, I am in pretty well the same boat

I have been quoted $242ea for adjustable Bilstiens, and without checking, hopefully I can use the springs of the Quantums

either way its going to be a bit of a pain in the ass. The way I look at it, is if one has gone, the others must be close, so it might pay for me to get brand new Bilstiens, which are fully re-buildable

    • I drive the Tiguan much harder than the Skyline in all conditions, because it just grips and hooks, unlike the R33 shit box
    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
