Is it too late to get in on this/is it going to happen?

Good things come to those who wait! Great effort to all involved.

Looking forward to those fresh springs, no rush tho!

Should have design solutions this week - then prototypes.

Just to reiterate a few key points:

P1 springs were made to fit an, already available, inverted kyb damper - and were subsequently sold off with a Bilstein damper that was designed for a higher rate spring set 35N/mm front and rear. Not the 34N/mm and 27.5N/mm of P1 spring set.

P1 springs do not match kyb agx's/excel-g's or koni inserts, for length - loose fit at full droop.
P1 springs are too high a rate for excel-g's - low speed movements of the damper - OK. High speed movements of the front damper - No.

How many variations are we looking at when they make them?

A P1 equivalent and a lowering spring suitable for KYB AGX?

The Plan:
Version of WR Blue - for excel-g's/agx's/koni inserts/early Bilsteins - ROAD
Version of WR Grey - for agx's/koni inserts/late Bilsteins - ROAD/TRACK
Version of Gymkhana/Tarmac - for agx's/koni inserts/re-rated Bilsteins - TRACK/ROAD
All of the above to be lower than P1's - minus 10mm front/6mm rear
Ensure Bilstein have access to the spring designs/rates for tweaking, when re-building - have provided Bilstein with test struts.
A set of P1 equivalents

Selection of bump stops being for measured/tested (for kyb/koni dampers); rather than, if possible, cutting down front and rear stops.

Why Eibach are prioritising designs for McClaren etc, over old Subaru's, I can't imagine - been promised something for this week.

Designs being checked over in Germany, this week.
Found suitable front and rear bump stops for the twin-tube shocks. Somewhat stiffer rear bump stops, to neutralise the chassis, without resorting to large rear bars - which, in road use, reduce comfort and the independence of the rear suspension, effecting traction.

Errr....you mean I'm suffering some kind of delusional episode?
I know I've had a very traumatic year, but I'm sure I've been to Eibach UK; and they are sending me design correspondence. So, no, on balance, I think it's true.

There's got to be a good option already for a decent suspension set-up for classic imprezas for UK roads, how about BC coilovers they're popular? This has taken way too long to sort out, it's been very interesting but too long a wait and no real end in sight.

You mean YOU'RE frustrated.

It's quite plain that small, independent, spring manufacturers can't get the designs right.
We've been lucky/persistant enough to get Eibach involved. We've also had great insight from the original p1/wr99 designer, who opened the door at Eibach.
I've also discovered the intricacies of anschlagpuffers:

Is it difficult to get springs designed and made, without a massive R&D budget? - Yes it is. Is it then, equally difficult, to get the correct bump stops, to work with your particular chassis and lowered springs? - Yes it is.

^^^ Fair points ^^^

I appreciate what you're doing, thank you. I'm just frustrated because my springs are creaking and the rest of the car is now really good (due to [email protected]).

Are both the front and rear bars adjustable?

LOL....and my cars been jacked up and down more often then a pair of ****** draws.
I lost count a long time ago how many times the various spring combinations have been on/off since last year.
Some of which have been a total waste of time with springs manufactured and supplied from the small independents.

It has become a little tedious to say the least......hopefully there is an end/solution in sight.

With regard to the comments about BC coilovers.....it's your choice.
But IMHO any coilover set coming in at under 1000 is never going to last or match the life/usability of a good set of MacPhersons and quality matched springs.
The coilovers also rust up in a remarkably short period of time, making their main selling point of adjustability totally redundant.

I agree, I'm not liking the idea coilovers for less than 1k or even for road use so that leaves the question of what struts and springs? Excel Gs seem like the right choice for a classic turbo and at a reasonable cost so that's sorted, but it's the springs to go with them that I need.

Cheers

KYB Excel G's are good, as are their adjustable AGX http://www.camskill.co.uk/m10b0s2611...TO_2000_Import

Thanks, those are a lot more expensive so I plan to stick with the Gs.

Greetings from the USA.

I would like to sign up as well, if possible.

I will post a thread at 2.5rs to see if anyone else would be interested.
