They are supposed to be designed to take away the negatives of normal poly bushes. I had a discussion about them last week with Matt Bentley I believe P11 COV had them fitted last year so may be worth getting his views You may also find this thread worth reading http://www.vx220.org...he-best-option/

[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]Ertacetal  still have the same basic issues as poly bushes, it's just a more engineered solution (material is tougher meaning it's wear rate is less, and groves in the metal inserts retain grease).[/color]

specifically:

 

 

never yet come across a car with [color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]Ertacetal/nylon/etc bushes fitted right..[/color]

 

usual issues are that no care has been taken to make sure that the bush'es themselves are a snug fit in the wishbones, usually the wishbone has some weld that sticks up and prevents the bush fitting home 100% and square or the like, then the tube is pushed in, and the bolt just clamps the whole lot together so tight that it all binds up.

 

sometimes the tube of the wishbone is a tad long/short so the bush tube is then too short/long.

 

basically, you have to 'fettle' the bushes to get them 100% right, and nobody seems to do this (especially when they are charging a fixed cost to do the job).

 

if done right, the bolts should be able to be torqued up and the wishbone should be easy to move (almost under it's own weight), but not 'loose'.

 

yes, they don't last forever, but assuming you're not giving them a salt bath every day etc, (or pressure washing them!), they only need a look at every year or so (and usually that's just a case of checking them and clean/regrease if required)

 

I don't like Polly because they usually are too sloppy and have serrated bush tubes that eat though the bush etc.

 

if you want compliance, use OEM ones, Lotus may be bad at many things, but they did a good job of specing them, the only real issue is they have a relatively short life.

"Fettle" is making light of the soul destroying job of getting them to fit correctly, it took me two full days to fit, install, remove, alter, fit, install remove, alter, fit...................ad infinitum.

What's worse is I spent all that time doing it correctly but doubt I'd have noticed the difference if I'd just bolted up and forgot about it.

Your words can hurt Simon, you've driven my car a number of times since the suspension refresh

Pah!

 

yes it's not a five minute job, but 2 days?

 

also, you don't have to fit then to the car to test their 'fit' putting a bolt through them and doing it up will suffice.

 

as I said before the biggest issue is that the way the wishbones are made can lead to some differences in tube length and some have weld bulges that get in the way, better to clean this off first than struggle later.

 

(in the old days they were a bit more hit and miss, but Gearys changed the design a while back.)

Didn't want to take too much off and fcuk em up by making them loose so did small adjustment until they felt right. The front uppers with the shims are not fun once but doing them a number of times made me want to drop the car on my head And you still didn't think they were done properly!

Can't say, not looked at them? (I'm good, but not that good!)

[Dave E]

I'll get Mike to drive it next time then

[rob999]

OE Dave, OE.....next time

[Dave E]

There're great now, just take a lot of work to get them there.

So is that bloke Matt Bentley is any good? D'you think he fitted mine properly?
