Koni FSD Part number dilemma

[trex]

Hello.
I've recently bought myself a 2001 1.4TDI 75BHP and i have a small question regarding the suspension upgrade involving Koni FSD's... what is the difference between purchasing the whole kit (2100-4041) and purchasing the individual 2Xfront and 2Xrear shocks (8710-1404Sport / 80-2830Sport)?
I'm asking this because the romanian Koni distributor quoted me at 551E for the whole kit and 155E for one front shock and 86E for one rear (482E the total).
Can anyone help me out?

Here are the wanted part numbers for each Koni FSD shock fitting Audi A2, Polo 9N, Seat Ibiza/Cordoba 6L and Skoda Fabia 6Y:

complete FSD set: #2100-4041

front dampers: #8745-1069

rear dampers: #8045-1070


These golden FSD dampers by KONI are characterised by automatic frequency selective rebound damping. They will improve ride comfort considearbly (please do a search here).







The below listed KONI part numbers on the other hand refer to the yellow (rebound damping adjustable) sport dampers for the A2:

Front: 8710-1404Sport

Rear: 80-2830Sport

These sport shocks should be used preferably with lowering springs up to minus 35 mm.




So your local dealer made a mistake and mixed up the part numbers of Koni FSD and SPORT. Koni yellow (sport) is always less expensive than Koni FSD.

Cheers

P.S. As far as I know Koni FSD shocks are not offered separately but only in a set of four (#2100-4041). However if one damper turns out to be faulty over the years, the Koni lifetime warranty will fill in (if you are the original owner of any type of brand new Koni shock).

Aha, now it makes sense!
The roads i travell on are rubish, and i've recently hit two gigant bumps while travelling at 90+ km... i felt my heart break, and later found out that i managed to scratch the lower part of the front bumper on the front right side of the car. On that portion of the road i'm used to travell at 120+ km's with my 2005 touran, and that's a heavy car...
I've heard that A2's have tight suspension settings, but this is ridiculous. That's why i'm thinking of investing on a set of FSD's. Is 550E a good price for the whole kit?

Is 550E a good price for the whole kit?

Yes - about EUR 550,- (including VAT) is the regular FSD set price over here in Germany too.

In addition to the in combination with stock height springs exceptionally well performing Koni FSD shocks you should also switch to 195/55R15 tyres plus lightweight 5 to 6“ wide 15“ rims to complete the suspension upgrade.

In terms of wheel related ride comfort a favourite could be the original Audi forged 15“ alloys (the polished ones) in combination with the inexpensive but well doing Falken ZIEX ZE-912 195/55 R15 85V TH summer tyre.

Are these the standard 15" polished type rims you are talking about?
I intend on using the FSD's with the standard suspension coils. It's enough i have to change perfectly good shock absorbers because they're not suited to the rough road going conditions, maybe new coils in the years to come.
Does anyone else have a better solution than the Koni FSD's to improving the car's capacity to handle uneven road surfaces? I'm not the "Schumacher round the bends" type of driver, altough i intend to invest in a remap later, but the capacity to deal with bumps or potholes and not feel like the car is going to buckle is my most important concearn.
Thanx.

Well I meant the 5,5x15“ forged and polished rims - pics below. These are probably the lightest original Audi 5x100 pattern 15“ rims available for the A2.

To reduce unsprung weight does directly promote ride comfort and does enhance breaking performance as well as traction. The recommendable 195 tyre width will protect the horn of a 5.5 wide rim effectively against kerbstone etc contacts.

Koni FSD do nicely deal even with very poor road conditions - please do a forum search. In terms of comfort improvement there's indeed no further alternative than Koni FSD (in combination with the standard height spring coils) worth mentioning except for Bilstein B6. But due to the automatic rebound adoption of the FSD technolopgy the Konis edge over the Bilsteins in total when talking comfort.

Do you know if the rims i posted above (that are already installed on my car) can acomodate 195/55 tyres?

 

[Schnelletrecker]

Your actual rims are sized 6x15 meaning a 195/55R15 tyre does fit perfectly.

Also sufficient rim horm protection is ensured.

Generally you can use the 195 tyre section up to a rim width of 7“. Some 195 tyres even are approved to be mounted to 7.5“ wide rims.

Koni FSD + Weitec spacers

After some further searching, i've seen that many people on this forum have a Koni FSD/Weitec setup. Does anybody know if i can use the FSD's with the Weitec spring spacers in order to highten up my car a bit?

Hello,

that mentioned Koni FSD/Weitec setup refers to the WEITEC 30/30 or 30/0 mm lowering springs working very well with the 1.4 TDIs and the FSIs. That combo is the best trade-off between car lowering and maintaining comfort for these “heavy“ A2s. However the lighter 1.4 A2 petrols should be upgraded preferably with the 30 mm ABT lowering springs (045VA + 046HA) plus Koni FSD for comfort reasons.

Does anybody know if i can use the FSD's with the Weitec spring spacers in order to highten up my car a bit?

Personally I would exclusively use Bilstein B6 shocks in combination with the 20 mm WEITEC “Spring Distance Kit" and stock height springs.

The reason to go for B6 is the altered body motion frequency of a car after increasing height. The special Koni FSD (frequency selective damping) valve control won’t operate properly potentially in a lifted car.
