  • S6 Custom Suspension?

    Does anyone know of a specialist up here North o' the Border who could sort out the ridiculous front suspension in my old S6?!

    I got Eibach springs front and rear and Bilstein shock absorbers but the front clearly sits higher than the rear. We have discussed this elsewhere on the forum but it's clear that Eibach cannot supply springs that allow the car to sit correctly. I initially had the S6 springs fitted which didn't lower the front end at all, whereas the rear end sat perfectly and still does.
    I complained to the UK dealer that the S6 springs were not lowering the front end of the car at all and were likely made for the V8 and not the 5 pot, hence the lack of lowering. I was then supplied the urS4 front springs, which are meant for the 5 pot. After fitting, the front end was then marginally lower by about an inch, but still the arch gap looks cavernous in comparison to the rear. There is approximately a 1" arch gap (perfect) on the rear and around a 2 1/4" gap on the front.

    I have yet to see an S6 which sits level and as you will see from John's recent photos of my S6 and Mike's, the difference between front and rear is very evident. I have long given up with the Eibach supplier as I was getting nowhere in spite of photographic evidence that there clearly is an issue here. Look at John's RS2 - it sits perfectly..

    Not surprisingly, the S6 had an even stance when new - I have no idea what happens to them during the course of their lives, but clearly after market springs have a lot to do with it. Here's the original sales brochure - they all sit nice and low and even >

    So, in short, I need someone who specializes in suspension up here to take my car and sort it properly - the mail order route is not an option any longer!

    Many thanks,

    This won't help you get any lower but if you want to level up the ride height you can either modify the rear shocks with extra slots to raise the circlip which holds the spring perch, or as I have done, use an aluminium spacer to raise the spring perch.

    It's common for the Eibach/Bilstein combination to cause this issue and there's been a lot of talk about it in the past. One company in the US used to sell spacers for the Bilstein shocks for this exact reason.

      The back end sits perfectly so I don't want to change it. Take a look at the clearances in that S6 brochure - nothing cavernous about the arches in any of those photos!

      Thanks for the suggestion anyway..

        I'll need to find out exactly what springs i have on the front of mine.
        Rears are Bilstein B462066 with eibach 1521002HA springs.

        I'll speak to the chap in Dundee who done the wheel alignment on my s2 see if he knows about the s6 front issue.

          In my opinion the only solution to lower it more in front and keep the Eibachs is to cut the lower spring perch and weld it a bit lower than it is now. I also have a set of E1516-140 Eibachs and have the same problem: to high up front and this is the only solution that i could think off. It shouldn't be too hard to do.

            Does anyone know the difference betwen 4A0411109A and 4A0411109? It says 2 lugs and 1 lug. Maybe one is a bit thiner and that could also be a solution to sit a bit lower, or maybe remove it completly

              Gene,

              Have a look at this thread - post # 228 in the link below.

              Eibach and H&R 29800 springs are discussed. They are discussed elsewhere in this thread I think or certainly in another of Wrath's threads as he had the exact same issue as you with the Eibach spring on his UrS6 saloon with it being too high in the front.

              Eibach will never fix the issue now, but they would have sold plenty of spring sets for a UrS6 if they had of got the front spring's ride height right.

              It seems to me that the Eibachs are softer and that they ride too high at the front of a UrS6. Softer than H&R is better, but the too high front ride height is a deal breaker for me and most others.

              H&R 29800 springs ride level but / and are harder.

              I put up with the additional hardness as I like the ride height and the handling, but while all the bushes are oem and the shocks are Bilstein, the tyres are 255/35/18 at 40psi so potholes and badly repaired roads / roads in bad condition are hard on the car, I know you prefer the 16' Avus oem rims on your UrS6, so 225/50(?)/16 tyres would help ease the hardness of the Bilstein / H&R 29800 set up, and probably be an ideal set up for you.

              While you will have to buy the H&R springs and pay to have them fitted, I feel it is the best worst option to deal with the ride height issue you have right now.

              Having custom progressive springs made up for the front would be good if the free length / ride height and the poundage could be determined.

              The H&R 29800 ride at a good level and stop the car looking like a 4x4 with the original oem springs, even the oem sport ones, but the H&Rs are not so low that speed ramps, and multistorey car parks etc. are a problem.

              Which part number is the Eibach spring kit that you have so that other UrS6 owners can be aware of the kit's part number ?

              Hope the above is of some assistance.

                Thanks for that information, MacBoingg. The original invoice I have here from TDC Automotive says the Eibach spring kit is serial no E1528-140. This might be for the original S6 lowering springs that I ordered and not the urS4 ones that were subsequently supplied after lots of complaining.

                Are you certain that those HR front springs will match the ride height of the rear Eibach ones that are fitted to my S6 just now? I don't mind the extra harshness, as you said, I have the Avus alloys with the Michelin Balloon tyres, as required for these Ayrshire roads!

                Cheers,

                Craig

                  My URS4 has Bilstein shocks front and rear with standard springs,

                  The rear is clearly lower than the front, maby the only way to cure it is Coilovers?

                    No worries, happy to share my experience.

                    I don't know, I was suggesting that you change out the four Eibach springs for four new H&R 29800 springs.

                      Well it is very important what rear springs have come with order under this common order number E1528-140, I did my homework when ordering mine and found this pieceof info -

                      Ausführungsbezeichnungen:
                      Fahrzeugzuordnung:
                      Vorderachsfeder:
                      EW 1515101 VA
                      4-Zylinder
                      Vorderachsfeder:
                      EW 1515001 VA
                      5- und 6-Zylinder, S4 mit Klima

                      EW 1521002 HA
                      nur Avant

                      In short there are 3 types of FRONT springs , and 2 types of REAR springs , all under the same order number

                      In shortER >

                      EW 1527001 VA
                      EW 1516002 HA

                      are the corect part numbers of the springs to be used on a sedan . ( and YES I did have to reposition rear perches - chose not to do grooves on the shocks but made 15mm spacers , bear in mind that as you raise the rear , there is more load on the front and it drops a little so it is not that bad. As for ride and handling , I am satisfied for a road daily car)

                      pls see attached file where spring size, ttl height etc are outlined.

                        Ok, MacS - that sounds like a plan. Can you recommend a stockist?

                            I have this exact kit in mine. Rear is a tiny bit higher than the front, but I like it.
