While i have you what do you think about the suggestion of uprating the bushes on the front wishbone as well i think VW racing mentioned it may also be a good idea to RedRobin but they have not looked into it as yet for him. so whats your thought's.

TT's quote

Uprated poly bushes on the leading edge of the lower wishbones (or indeed on any suspension component) are a bit of a grey area.  Yes, they will marginally improve the feel, and generall handling.  However, they are no where near as compliant as the standard rubber bushes.  Poly suspension bushes, which include the WALK, will give more noise through the car, and will create much more harsh "feelings" inside the car.  If you have a wife or kids, or generally enjoy the refinement of the car, I would just stick with the WALK, and leave the front bushes standard.

Just remember that VW Racing are race car or motorsport specialists.  You need someone who knows what works best on the road.

....And I will refer to what I have already written and add that the bottom line is what each individual wants from their GTI/Ed30. Having driven two GTI's with polybushes throughout I personally didn't find it to be the problem I expected. But ETTO.

Actually, thinking about this a bit more, if you are fitting mods such as WALK's and coilovers etc, you are already entering the twilight world of the overlap between road and track. So I don't agree with what TT has said about VWR's 'limited' knowledge of fast road needs. Furthermore you have already 'compromised' the "feelings" inside the car. It's the difference in compliance between the WALK's and stock bushes which I am pointing out may be wise to address.

Hi,

I'll chip in a little and say I tend to agree with RR/VWR, as I can see the logic in what they're saying.

The standard bush is at least a solid one, rather than voided and is a pretty hard compound for OEM kit, so it is better than it could be. I certainly think it is up to the task, but you've got to be mindful that it will wear a bit quicker. I'd be interested to hear what Whiteline suggest on the matter, as it must have been a consideration and wouldn't be hard for them to add it into the kit?? I'll ask them.

I guess I'll just wait and see what happens with it, it might last 12 months, it might last 3 years? but I will have it checked regularly.. 3 solid days at the 'ring last month and all day at Donnington yesterday shows no issues so far and I guess mine will be the acid test car as it'll get more sustained hard action than most.

I have no reservations about polying the front end, I've had my previous cars done and never noticed a negative difference - although I've never run a super-hard, decked car.. maybe it'd be more apparent here? I'm going to be upgrading the Eibachs for Bilstein B16s come spring so will have them swapped out at the same time for poly anyway.

Thanks for your very useful input, tony_d. :happy2:

Yes, we're not saying that the stock bush isn't up to it but only that it becomes a potentially weaker spot when the WALK's are fitted, and that ideally they are better changed.

However, I do respect TT's point about comfort even though I don't think just replacing these bushes will make a noticeable difference.

We should bear in mind that VWR and those in the racing world will be much more inclined to go for the 'ideal', but because of the way I am and my intentions to keep my GTI, I go for the same ideal.

The purpose of my posting such info/advice is to help rather than to ring alarm bells.

:happy2:

tony_danza:
Yeah, T_T's point is a fair one. Poly in some applications can be terrible, I'll give you rear beam bushes or a dogbone on a MKIV for starters!

Rubber tends to be used in wishbones not so much for the compliance/comfort, but the ability it has to reduce noise. Polys (depending on how hard) can slightly increase tyre roar in the cabin. However, the benefits of their control far outweigh this problem as they allow the suspension to work on its correct axis without being distorted by lateral forces.

Danza's conclusion:.. if it'd have been a voided bush, it would have been swapped out, no questions.
On a road goer, I can't see it making a significant difference to the lifespan of the bush although the possibility is there and is to be considered.
For tracking, in hindsight I'd have poly'd it but I'm not going out of my way to change it now, I'm confident in its ability, as must Whiteline be too.  They've been making these for years now on scoobies etc. and it would have cost them pennies to chuck in a front bush - they obviously deem it good enough, but there's absolutely no harm in a bit of preventative action like VWR have suggested in the "belt and braces" approach.

Don't forget, tracking is very, very hard on a car - I'd ruin a set of topmounts every say 3-4 events, but even fast road would see them go for 30k. VWR have evaluated it based on their needs, so I can see exactly why they'd want it uprated.

Top Cat:
Its all good info. This thread is excellent, lets hope we get a few more like this.  :drinking:
