Indecision killing me- which coilovers spax or gaz?


ORIGINAL: wibble
I have also considered the Koni option, but cannot be bothered with cutting struts and being sprayed with hydraulic oil.
It's really no big deal. I did it, and it's less than 90 minutes work all in, for both sides.

Don't rule out the Koni option just because of a bit of metalwork. In terms of cost and value, the Koni option was the cheapest when I looked into it (3 years ago or so) and one of the best. In terms of value (i.e. £/unit improvement), it's an excellent option.

I have considered the KWs, but think it's an overkill for just the sunday fast road.

Its not, its chalk and cheese.

All you undeciders need to drive a car on KW, its not just good on track but it makes a massive difference on the road even if you never go near a circuit. The spring rates and damping are spot on and the bypass valve soaks up large bumps and potholes etc brilliantly so the car isnt unsettled.

Well worth it, if you intend to keep your car then you need to try it and you will be a convert. Most are.
 
This is an interesting topic!

The SPAX PSX kit which has a 30mm drop and adjustable stiffness for less than £400 seems a bit of a bargain for a road car - I just can't see myself adjusting the ride height at all and don't even think my car will see a track day more than twice a year so why pay for that? I'm sure many others are the same. The SPAX kits are powder coated too, and after seeing how the GAZ shocks corrode I'm less drawn to them.

The question is - will the rear need reindexing with a bolt on 30mm drop kit like this or the RSX from SPAX & others?
 
Lets dispel one myth. KW stuff is not specifically road orientated stuff and it is in no way 'soft'. It was designed for track work and is as good as any other comparable kit out there if not better. The valving in the damper gives the impression of 'softness' but it is not soft. With my old car on stock ARB's the car cornered as flat as a pancake - that is not the trait of a soft set up. KW's are stiff and you can always spec stiffer if you want, but the standard v3's are an excellent compromise for fast road set up and a setup that will not leave you wanting on track. Clearly for a dedicated track car on slicks you'll want stiffer. It is a myth that for track work you want rock solid suspension - as Pauly says, go for the softest setup you can get away with.

KW seems expensive but they are good value for money. Equivalent to a mid-range mountain bike, a decent spec PC and if you're into a sport like diving you'll be spending alot more on kit. I'm currently looking at buying a TV that is more expensive than KW coilovers and you can bet your bottom dollar the KW will outlive a TV. So if you consider your car as a hobby, like diving, then it is a very reasonable price for a piece of kit.

I had a good mid range set of dampers on my trackday golf. One has failed so I needed another set. The ones I had are very well considered however I took advice and tried others with differing suspensions and have gone for a more premium type as the ride as a whole when taken into account was much better with better more progressive spring rates and damping. I would have gone to KW but they would be more than I paid for the car so a sensible compromise ensued.

Again, I really do recommend you try (if possible) before you buy. Low cost suspension is low cost for a reason.

Having said all that, you need to consider it as a whole for no new dampers/springs etc will make up for worn bushes etc.

Scott is correct in the the KW is `firm` but not in an unsettling way. It does communicate more into the car but the trade off is a transformation in the cars dynamics. An improvement on its original suspension in my view, hower, again its all part of a whole that needs consideration.

To summarise, get a less costly set up as I`m sure it will be an improvement but also consider the suspension bushes so as to get full benefit.

Regardless, good luck anyway [:)]
 
I bought a SPAX kit and am very happy with it. Build quality is good, powder coated body with the relevant brackets for brake pipes etc. The threaded collar is made of stainless steel with aluminium anodised spring supports.
The car has 18 inch wheels on and I have to say the ride is really good, granted not as good as it would be on 17's I'm sure.
The SPAX kit is rebound adjustable front and rear - easily accessible and height adjustable at the front.
The car had a wheel alignment last weekend at Promax, Anthony the technician there obviously drove the car and was impressed with the ride.
In my eyes the kit is a dam good road kit and is a huge improvement over tired stock suspension, it is not a track kit in any way which suits me.

Purchased from Silverstone Tuning.

Hi, What's the spring rate on the spax kit,does it match the stock torsion bars?
