I bought my Sprint Gaz ASP shox from the TSSC and they were correct, so I would assume that they have the correct part numbers!

Unfortunately mine are no longer legible so I can't confirm it!

I bought them from the TSSC cos theirs was the best price! May not still be so, but worth checking!

Yes their prices are very good!

I assume you have to be a member to buy parts as I will be looking at a similar set up to replace my tired SPAX. Joining just for this wont be economical for me.

Yes you have to be a member but beware - I had to cancel my order with them because:

A) The adverts are misleading in my opinion, showing TWO shocks with the description being a PAIR but the price is for one only (you only realise that when they send you an email and request more funds for the order!)

B) The photos of the rear shocks do not have a seat for the spring. When I pointed this out they were at a loss to explain it.

So, as it is a good sum of money, I cancelled the order and went to people who know what they are talking about - Merlin Motorsports - and their prices are very close to those of the TSSC.

I purchased my Gaz Front & Rear height & damping adjustable shocks from rimmers.

I searched around on the internet and found them for as cheap as i could and then got rimmers to price match.

Have had them on the car a few months now and very happy with them!

Does anyone have the model numbers for the front and rear GAZ adjustable shocks?

The TSSC lists GS1-2266 or GP6-2267 for the front and GP6-2268 for the rear. Are these correct?
Can anyone confirm if those numbers right?

The set of rear Gaz shocks that I recently auctioned on Jon Tilson's things had the serial number GSO 2264; they had adjustable ride, but fixed platform

No one has spoken of a rear anti roll bar? I have fitted one on my car to try.
Conventional wisdom is that a rear ARB doesn't always work on a live axle and I have to say that it has made the front feel vague now, although the rear feels good?
It is running Spax dampers and springs and some polybushing (replacing standard material when they wear out!)
As the car is mainly used for rallying and limited to 70 series tyres I don't have the luxury of grippy Toyos (although I do have some 60 series Yoko`s when regs allow).

Does anyone have experience of uprated front ARB`s? in years gone by I have made up twin arb`s on Ford`s (a common mod back in the day when parts were hard to come by)

I'm running a rear ARB on my own road/track car, just a stock Sprint one and I think it helps more than hinders. But my car is so far from from stock, with it's Vauxhall powerplant, lightened, short tailed, 2 door body, altered CofG, modified suspension etc, that my experience is largely irrelevant!

The factory circuit cars, compelled to use a rear ARB (because the production cars had one) used one that effectively was a piece of piano wire that did nothing - Which may be a clue to the works engineers (and the drivers) opinion of how needed it is! But AFAIK the works cars all had LSDs which also affects handling and balance. The wisdom around here, such as it is, seems to be "suck it and see" some prefer with, some without, depending on how "loose" they like the tail to be!

There is an almost mythical, fatter, front antiroll bar that was allegedly fitted to very early Sprints but dropped almost straightaway in favor of the now standard one. Or it may have been a short lived ST part. Whatever, it's only ALMOST mythical as examples DO exist, but are less common than hen's teeth! As far as I am aware, nobody has produced anything like it for the aftermarket, which, I would say, demonstrates a lack of demand (or need)

I've got VA138 (L reg Sprint) and I've measured the front ARB tonight and it's around dia20mm which is the same dia as the one on my P reg one....

Thanks for that Shaun, but it's not really definitive, anything could have happenened in 45 years! Admittedly VA138 is early enough that if it WAS an early car only fitment, it's early enough to be so fitted. BUT, assuming the fat bar was so detrimental to handling that the factory sought to replace it so quickly in production, it may have been recalled - or it may have been swapped out later in life either in ignorance or by design, or even to provide a fat bar for a more performance oriented car. Or it may not have had one at all and the fat bar comes from a different source! We can only speculate!

Apparently (and this is little more than hearsay) the fat bar is 24mm. I did hear a rumour that "dolly nut" had or has one!

After many years of racing I ended up with a front ARB that was twice the cross sectional area of the standard. The ends had adjustable linkages to the suspension. Rear ARB was never used. Firstly, if you don't have an LSD the priority is to try to keep both rear wheels on the ground with as much pressure as you can so the inside wheel doesn't lose traction. Even with an LSD, driving with no rear ARB produced the best lap times. Cornering with only one front wheel on the tarmac looks good too, yet seemed to produce the most stable fast cornering, allowing a good balance to be maintained between under and oversteer just by adjusting the amount of throttle.
Still suffering from withdrawal symptoms!
Geoff

PS I did try out a thicker diameter rear ARB, but only for half a meeting. The fastest way to end up swapping ends I ever came across. Never experienced oversteer like it!
