KW Variant 1 Coilovers

[Yaz]

To Macspring & Jamo, there seems to be a slight difference in price and it also appears that the S2 Avant has a slightly heavier axle load weight at the rear and another factor is that the RS2 has more BHP so I would assume spring rates differs slightly. This applies for the V1's as well as V3's.

Let me know if you need any further clarification on that info as I can contact KW directly with the question.

Also interested in this. Thanks Jamo for asking.

I'm interested in a set for my typ85 90. I'm swapping to s2 hubs etc soon. Has anybody fitted these recently? The car is a weekend toy so handling wins over cumfort so want to know how they behave on the road and track. Cheers!

There is a member on here 'SE_30' who has the same vehicle with S2 setup and all being well he's going for V3's, might be worth asking him soon

I'd be interested in what KW have to say about this too...

Right, due to popular demand and the fact that its made me curious too, I have put the question the KW UK who will liaise with the tech dept in Germany and get back to me in due course.
I will endeavour to update all once the relevant info has been passed to me!

Many thanks

Quite a bit of discussion over the years about the OE and HnR Avant vs. RS2 suspension, so will be interesting what KW say. OE RS2 springs are the same as Avant aircon springs and IIRC, the HnR TÜV papers indicate that the springs are the same but are a different colour.

Are you able to supply spares from KW? I need a replacement rear bump stop with the two brass collar insert for a kit fitted to a 1990 Audi coupe 2.3 10v 2wd.
Would you be able to assist?

Thanks

Well there has been an update from KW tech dept who have said that there isn't much difference between the S2 Avant and RS2 suspension in terms of physical appearance, however:
Firstly, the reason there are two different part numbers is because the RS2 kits weren't available until much after the S2 kits were released due to the requirement of further research and development.

Secondly, the RS2 kit takes slightly lighter weight on the rear axle compared to the S2 Avant, so the spring rates are different at the rear slightly.

Thirdly, RS2 kits only come in M14 strut bolt sizes (1 part number) and the S2 Avant has either M12 or M14 strut bolt sizes (2 part numbers).

So to summarise, the RS2 kits cost slightly more than S2 Avant as the rear axle weights are different and more in-depth R&D was required prior to manufacture.

I hope this answers your questions, but please do not hesitate to let me know otherwise.

Many thanks

Hi Gav, i'm more than willing to try for you mate. Do you know what kit you have, i.e. V1 or V3 etc? Also, would it be too much trouble to take a pic of the brass collar insert and PM it to me?

Once you send me this info, then i'll contact KW for you

Many thanks
Yaz

I have no idea where they got the s2 avant rear is heavier than the rs2 rear as its book weight is more than the avant by 35 kg!
Good info Though

Yeah I know what you mean, it doesn't appear to make sense but there must be some difference somewhere...

My personal opinion (feel free to correct me!) the RS2 is more powerful from factory as an S2, so perhaps they felt that the rears had to be a bit firmer to accommodate this when accelerating fast from stand still as the rear end does squat down on these cars right? And more power on launch = more squat!

Or shall I just quit whilst....

[Jamo]

I agree with you, but I can't see why the rs2 is lighter, same chassis, same subframe, diff, wishbonnes, they have differrent uprights and brakes but not 100 kg weight difference

If i'm luck enough to have spare cash i'll get the rs2 kit though

PM me when you're ready!

Smells a bit funny to me...

Softer springs give more understeer (and more squat, not less), so they've just been safer with the faster car. The ARBs are different on the RS2 but not by much and the stiffer front bar is going to make things worse. So, if you want more understeer then go for the softer rears on the RS2 setup

[Jamo]

The fronts are rated for more weight than the Avant setup would be my thinking

Right, I have a bit more clarification which I was happy with the sound of...
Basically KW are saying that the RS2 has what they call the 'P1' platform which is different to the 'B4' S2 Avant platform. The R&D was more involved with the RS2 at the time and the components used within the dampers for the RS2 is different to the S2 kits. The valving setup is different.

This to me seems perfectly feasible as to the reason for two different part numbers and slightly higher price for the RS2 kit.

Another thing to bear in mind that the components required to assemble an S2 kit are more available as they are used in other similar models too (non S2), where as the RS2 has its own unique components which is not shared with any other kits.

I hope this clears things up a bit?

Many thanks
