i also have recently fitted the Protechs from SJ Sportcars and was told at the right setting they closely resemble original spec handling. i also think, compared to the shocks ive fitted on lots of other cars, that their well made for the money. i fitted new road springs at the same time. hopefully we wont have any probs with them so i would recommend the protechs. regards. DC.

I have had Protechs for a couple of years with no problems

At the time I phoned AVO to see if I was missing something obvious, but they were "unable to give advice on a specific vehicle" - which again is daft because that particular model of shock was unique to the Excel. They suggested talking to the supplier, who was Christopher Neil.
Christopher Neil's response on the phone: "I'll just get one from the stores and have a look. Oh yes, I see what you mean, they look fatter than the ones we've been fitting for years..."
Unimpressed. Go with Gaz...
Try Talking to Mike Taylor................if he's happy .........so am I..........the only issue with AVO was there finish quality but i can attest to the improvements..........Lets not forget the AVOs i am talking about are a different suspension set up i.e. Coil overs andnot the standard coil and shocker, + they are adjustable both in rebound and in spring adjustment.
I have just looked to purchase new shockers for my Mk1 Eunos and the original set up are £80 per corner without springs.......
and that is a Jap toy.......... I paid £110 a corner for AVO coilovers with springs and they are adjustable................

I just think that if the ride and handling are so coveted with the original set up, why change? Fair enough if Lotus themselves developed improved ones specifically for the Excel but I wonder how much development work went into shockers by AVO etc for the Lotus Excel.
I guess what I'm trying to say (none too articulately) is that although damper technology has undoubtedly moved on in leaps and bounds, are the replacements that AVO and such make for the Excel tuned with as much care as the Lotus ones. Technological advances verses Lotus unmatched skill / experience / expertise in chassis dynamics I suppose is the point I'm making.
Maybe a seperate thread on peoples experiences with dampers would be interesting (presuming that the improvements noted by replacing with non standard arent just the improvements you would expect from replacing shot standard dampers) Personally I'd love it if AVO and Protech are genuinely better as they are what the previous owner fitted on my car.

With the Protech (which I have) do you know "... SJ Sportcars and was told at the right setting they closely resemble original spec handling..." what the 'right' setting would be?

Not a clue - I tweaked them to suit the way I drive - the adjustment is via a little thumbwheel on each damper (had to modify my rear suspension a little to make a cut-out for easier access to it) so easy enough to do. I think I've got them set about 2/3 of the way to their "stiffest" setting and cornering is excellent.
Some thoughts on adjustable AVOs have been posted before :

Steve at SJ Sportscars said from the 'o' setting 9 clicks at the front and 6 at the back on Protechs. car feels the same/original handling to me. Regards DC.

Maybe I'd be waisting my time changing back to OEM then

Last week I treat my Excel to a pair of Gaz Gold adjustable rear dampers. I ducked out of fitting them myself and opted to have them fitted by Colin at Revline, Whitley Bay.
I'm pleased with them so far and at the moment have them set on 14 clicks which seems to be a good compromise between handling and ride comfort.

My rear GAZ dampers are now "misting" so are due for replacement after not a lot of miles but to be fair they've been on the car for about 5-6 years and IIRC, they didn't come with dust covers. I had GAZ on the Clan and they soon "knocked" (these defo didn't come with dust covers) so went to Protechs (with dust covers) but haven't done enough miles to assess longevity.
On the subject of GAZ settings, many years ago I first set them at halfway to assess them on the rear and seem really good until I drove a twisty bumpy B road at speed which showed them to be too soft (pitch roll /unstable/relative understeer). It's easy to adjust the rears on the road so I experimented and settled on a setting of 17 clicks at the rear. (Front are OEM (!) and will be replaced along with rears!)

Matt.
Be carefull changing the ARB to lower arm bushes. The replacement rubber ones are very hard and difficult to change. I split 2 trying to get them in and there not cheap. I would leave the old ones in

The Protech rear dampers I had fitted five years/8000 miles ago now need replacing again. Not impressed! Hoping to find some Spax this time.

Yes but to be fair, my Clan's Spax AND Gaz got 'valve knock' just as quickly if not quicker. The GAZ on the Excel leaked prematurely ...except they were not fitted with covers so I can say that's more likely my fault rather than bad seals.
Have your Protechs leaked or are they knocking or just gone soft?
Maybe they just don't make ANY of them like they used to / generic Chinese parts?

My '83 is on it's original springs and front shocks.
I changed the rear shocks about 20 years ago for OE Lotus items,(Armstrong?) after an MOT fail.
It's probably time for a refresh to be honest, I've noticed that the trolly jack is a bit of a tight fit now!
I'd like to go for plain simple like-for-like non adjustable if such a thing is still available?
. . . following this thread with interest.

The knocking alerted me to the fact that something was amiss. On removal I find there is half an inch of free movement, i.e. undamped travel, on the offside unit.
