Default Gaz gold, ast sport line 1, bilstein setup

Taking into account the prices, what would you use for a 70% track car
Gaz gold with ast top mounts
Ast sportline 1 with track springs
Gaz gha with ast top mounts
Custom setup, with rally design conversion, bilstein group n's and Faulkner coilover springs

AST's or bilstein out of those, Gaz internals are utter crap not what you want on a track car Billys and AST are decent quality inside and out

Leads but will cost you Bit, ohlins but will cost you a small fortune , you could have a machine shop spark erode a thread on the boddy and get it annodised (you can anno steel)

Gaz gold setup, as it can be a tailored package, easily servicable, with quick turnaround. lots of adjustment. Not heard of many units failing?

AST are good dampers, although i think sportline 2 would be more on par with the golds.... and if you want to wait a lifetime for delivery and any type of servicing there you guys...

Bilstein, good dampers, but the group n's arent in the same league as the above setups.

Ive got golds the same as what olly and unreal aka tom have got and really rate them, the ast sportline 1's are only about 12 point adjustment where as golds are about 32 i think. Camber built into strut where as ast you would have to buy the top mounts £330 extra.

Billies dont have adjustable damping/rebound.

dosnt make the slightest bit of difference how many clicks they have, as the incremental nature of the adjuster will differ

take sachs matrix dampers for instance these have 16 clicks for lowspeed and 8 for high, ohlins TTX have about 32 for low and 48 for high but both sachs and ohlins dampers can adjust to the same overall percentage depending on what internals the adjusters have, and knowing what gaz and ast look like on the damper dyno nether offer a great range of adjustment in comparison to better brands.

and the way gaz dampers operate with gas filled bags rather than a dividing piston system, this incurs loads of lag this is when the damper moves without offering any damping at all.

so in short as far as i'm concerned gaz are shit even for a road car, this is my professional opinion after dealing first hand with the above mentioned dampers

ohh and the valving in gaz dampers is ancient loads of rebound and sod all compression damping for the same movement this was used back in the 50's now even the most basic of car dampers have a better balanced rebound and compression correlation

sorry to burst the bubble of those who own gaz dampers but unless you just want a slammed look then look elsewhere, and dont touch with a barge pole for track use

Barwell, fair comments, i have no grounds to say if there true or not, but maybe your going a little out of context with your responce?

dont speel off about ohlins/sachs/leda (out of business now) when the guy is asking on a general trackday section of a saxo forum, there a little far fetched.

i stand by my comments, and opinions above. i dont know how many 70% use trackday cars there are out there using sachs setups, and what your suggesting is the stock road dampers are better than anything other than motorsport setups.

Cant believe youve burst my bubble aswell. i thought gaz were the dogs danglies of dampers.

For quality oem are better than gaz I know öhlins are a bit out of the legue of most that's why I tried to keep the comparison between the 3 mentioned brands just used öhlins and Sachs as a example with the adjusters

As said I don't believe that gaz are good for any thing but looks, ast are ok, although we've had a few problems with what we've seen but at least the quality is 10x's that of gaz bilsteins are simple and just work although the lack of adjustment is a put off for most

I'm not trying to get people buying öhlins far from it I just want people to be aware what they are buying from a technical point of view and a professional oppinion on the quality of the stuf, in the damping world quality is every thing , to get two dampers to match they must be made exactly the same as any deviation in the machining could throw one damper off as much a 500nm at 1mm of movement per second we aim to be withing 100nm at the largest variance in force over displacement, and gaz just don't have that sort of quality

But hey if that's what you want then go for it

Barwell - I agree that yes there are better dampers and set ups out there but based on my and olly / jsdvtr personal experiences with the dampers from GAZ are fantastic therefore I would recommend them to anyone and ask anyone who has been out in my car with an identical set up the one mentioned they will tell you how "neutral" and "planted" the car feels.

From a driving experience the car is very sure footed and whatever the driver inputs the outputs are very predictable making for a quick car.

would I buy GAZ again - Definitely

I used to have a apex kit on my car before changing to gaz golds, they were ok for shortened dampers on a road car but when i put the gazs on they completely changed the car.

All these other suspension companies your suggesting ive heard off but dont know much about and are probably going to be alot more pricewise in comparison to the gazs and the ast sportline 1s. If you was building a cup/full on track car and had the money to spend on the best then fair enough.

Also about the point adjustment on the dampers i.e. 32, 12, etc. Surely the more point adjustment you have the better you can fine tune the damping?

The thing is that a suspension kit is great until you have tried better.
AST certainly outperform GAZ in racing but the bottom line is how much ££ you are prepared to spend. A set of Gold coilovers are under a grand and will get people out on track with a fast and stable car.

As for worrying about how much a damper is adjustable - well sometimes a high quality damper simply does not need it. The Bilsteins are excellent out the box but they are not damped for a pure track car but for rougher surfaces as you ideally will be running at least 300 lb springs on track. They have variable valves inside that adjust to the loads running through the suspension which saves you from cocking up the setup twiddling dials.

We've decided to work with a different company and develop something better for the hardcore track crowd. Not cheap though

Hmm, that's not too bad, fairly sure at least 2 are mine are on the way out, there's definitely a lot of build up around the top of the seals. They're only about 15 months old.
