Pictures of my H&R Cup Kit and struts

[porkkis]

Yes. I know that all t89 quattros have M55 rear shocks. All of them. All

The front ones are M50 at all others than S2 coupe. It's the only M55 one that uses thick shocks up front.

If you're planning to use bilsteins with stock springs you should go for the sport versions not sprint!

SPORT vs SPRINT

Why use the sport other than the sprint if you are lowering the car?
I see from the Bilstein catalog that there are no "sprint" listed fir the s2 with M55 X 1.5
strut diameter. Is this the reason?
Thanks, Chris

That's the reason but the front is no problem. The rear is with some lowering springs.

[A1QSHIP]

OK, it was my impression that the "sprint" strut insert was shorter to work with shorter springs. If the dampening values are the same for the sprint & the sport, why would it be better to use the sport in the rear rather than the sprint? I had intended to use the sprint all the way around on my USA version coupe.

With stock springs as Rafael is going to!!!

If you have shorter springs go for the sprint.

Sorry for not being completely clear on this.

Hmm. In the U.S., the European "Sprints" are called "Sports" and the European "Sports" are "HDs" (Heavy Duty).

My take on the posts above is that you have to use the regular ones in the rear (U.S. HD/Euro Sport), because they don't make the shorter one. So, it's not that it's better, but that it's "possible".

Is that correct?

That's the reason...<snip>

The catalogue showed no front "sprint" for the front of the s2 which has a strut tube with M55 X 1.5.
There was a "sprint" for the vehicles with the M55 X1.5 strut used in the rear which is in all the type 89s as has been posted here in this thread.
There is a "sprint" for the front strut tubes with M50 X 1.5 .
I have found a Ground Control coil over kit for the 4000s quattro (US spec car).
The kit uses two different sized threaded sleves that have an internal diameter of 50mm & 55mm. The kit uses Eibach springs 340#s in the front & 280#s for the rear. Front sprilng lenghth front 8 inches, rear 9 inches. Originally, I had intended to use the front strut tubes off of a B4 (V-6 powered sedan in US) since they use the larger diameter M55 size. Since there is no "sprint" strut for that diameter, plans have changed.

http://www.2bennett.com offers a coilover application for Coupe quattros, for anyone who wasn't aware of that. I have no experience with that particular setup from them.

Stop the bus - this thread is VERY confusing now...

Can someone explain from the start again as all I'm seeing isn't going anywhere towards a resolution here !

I'll try

- bilsteins are offered as B6 sport and B8 sprint
- B6 = normal length sport type shock
- B8 = shortened
- s2 coupe always has M55 front shocks
- B8 sprint is not available as a M55 front version
- All typ89 quattros have M55 rear shocks
- Bilstein offer both B6 and B8 for our rear axle
- H&R has the set that comes with Bilstein shocks, they're B6 front and B8 back

- Normal length rear shock (B6) combined with H&R rear spring will not create about any pre load
- That's why H&R supplies their set with B8 rears
- Front is not a problem as the spring is slightly longer

- Rafael should go for B6 all round as he is going to use standard springs

[The Spanish]

Let me try to explain easilly.

Bilstein produces two range of shocks for the Coupe:
Bilsteins Sport (for standard height)
Bilsteins sprint (for reduced height)

Bilstein Sport.
Front: PE3-3086 (M55 thread) All S2
Front: P30-3005 (M52 thread) Non S2 coupe

Rear P30-3017 All Coupe (S2 and non S2)

Bilstein Sprint.
Front: P30-3006 (M52 thread) Wich kind of rules out S2 but ok for CQ conversions
Rear: P36-3058 All Coupes

So if you have an S2 coupe and want standard height is: PE3-3086 front and P30-3017 rear.
For Coupe Quattro and standard height: P30-3005 front and P30-3017 rear

With H&R springs in the S2:
Front: PE3-3086 (Although not really made to them) Rear: P36-3058
Non S2, Front P30-3006 rear: P36-3058

I dont know if the M52 thread can be converted to M55 my machining 3mm and then you can use the P30-3006 on the front on the S2 with H&R.

Cheers

You were faster Petri

[Jonas_R]

Porkiss you are talking about pre load? What is this, can you explain?

Have you fitted your kit yet?

/Jonas R.

[porkkis]

I'll fit the kit when I'll change to summer tyres. Not for a month or so.

With preload I mean how much the spring is compressed when the top mount is bolted on the strut. If the shocks are too long or the springs too short the springs won't compress a bit. This is something our MOT does not allow. The springs must be tight in place even if the wheel is raised from the ground.

The 30-3006 is the listed sprint shock for the ABY, as posted in another thread the 3B is different size to the ABY
