Dohhhh. Just realised the wire diameters were in that quote too. Must learn to read before posting..... :oops:

as long as the dampers suit, either will do.

They're supplying me with three kits of four dampers and springs. So if there was a cock up I'm sure they'd notice. I've asked them to confirm all the specs anyway.

Steve,
Are you going 'coil Over' inboard or what ?

These are for a 5A Viv. Staying outboard for the SS1 fronts. I'm not sure there's enough room to fit coil overs at the front with a DET installed. It's very tight ! Chris had to shave one of pulleys of the tripple pulley wheel to get it to fit.

Steve,
OK, my misunderstanding, it was very late/early this morning (?) when i read it :oops: I have 2.5" all round on my 5a, and also Tina's 6a, and would question why go to a 2.25" on the 5a as the 5a weight will ensure that you require the shocker to work harder than an equivalent 2.25" on an SS1. Just posing the question as undecided/unconvinced of either Benefits/Drawbacks.
Regards,
Viv

I need to double check what they supplied for my GTC. But if it was 2.5" front and 2.25" rears, they were very good indeed. The shocks are the GAZ standard catalogue items and not anything custom. So whatever the spec turns out to be, it will be what they usually supply.

Viv, I'm confused by that. Surely there's no difference between a 2.5 in diameter spring of a given poundage and free length, and a 2.25 in diameter one of the same poundage and free length, apart from the diameter? the dampers will be the same, apart from the size of the spring seats - I've changed between 2.5" and 2.25" springs, on the same dampers, simply by changing the spring seats. If you're likely to want to experiment with different spring specs, then 2.25 have the advantage of wider availability. (I'm of course assuming that we're talking about ride-height adjustable dampers) :? Or am I missing something?

yep - it's purely a size and weight advantage as far as I can see - the spring effect will be identical whether the ID is 2.5", 2.25" or 1.9"?

Unless...you can get more internal gubbins into a 2.5" damper casing than a 2.25" - is that what you meant, Viv? Something tells me it'll be the same guts (and maybe the same casing) anyway in the interests of mass (!) production.

Dodger,
As Jim said it's size/weight advantage/disadvantage dependent on what's used and I have stayed with 2.5" Koni/Spax/AVO options on the GTE's (ie. having tried:- Boge/Monroe/Armstrong/Girling) as when they were built there were very limited, if at all, options for 2.25" sized shockers. By the time the SS1s/SSTs/Sabres came around then the small hatch explosion had fuelled the requirement for 'go-faster' 2.23" shock/spring combinations however IIRC the SS1s/SSTs/Sabres still had the 2.5" ID spring/shockers as standard on the rear. I would guess by now that the vast majority of the 'go faster' SS1/SST/Sabre owners will have opted for 2.25". I know I have however - Jim, I'm still undecided on the Protech Shockers on 8Ball - any feedback yet ?
Regards,
Viv

Yes, and I also agree with Jim, i.e. I don't see any practical difference (beyond size & weight) between 2.5 & 2.25 in terms of their use, assuming you're going for adjustable spring seat dampers, which in my experience will normally take either 2.5 or 2.25 spring seats. There is the much wider availability and lower price of springs in 2.25" to consider though. Your original note talked about the "shocker working harder" - that was what I was questioning, and still don't follow. :?

Dodger,
I thought I was referring to the weight of a GTE verses SS1 !

weight of car doesn't matter to ID of springs - the 1.9" protech are for the SS1 Viv.

Jim,
I didn't say it did, what I thought I said was that the same shocker whether it be 2.25" or 2.5" (or even 1.9") will work harder with the weight of a GTE as opposed to the weight of an SS1 - or am I missing something here ?

Viv
