TarkMalbot Posted April 8, 2009 Report Share Posted April 8, 2009 I ave come accros these: http://www.powerflex.co.uk/products/MX5+MK...+on-2621/1.html Are they worth the money? Do they make much of a difference? Are they difficult to fit? Will the cars geometry need setting up again? Quote Link to comment Share on other sites More sharing options...
Janey Posted April 9, 2009 Report Share Posted April 9, 2009 Yes to all of the above They are worth it & they do make a noticeable difference. They can be tricky to fit (main problem is getting the old ones off) and yes I'm guessing the car would need setting up again as you are more than likely removing/undoing things like wishbones & track control arms to fit them. Tony would probably be better clarifying this as he knows the underneath of a 5 better than most Quote Link to comment Share on other sites More sharing options...
CIH Posted April 9, 2009 Report Share Posted April 9, 2009 I wouldn't expect an NC to be old enough to warrant a bush replacement/upgrade ? Quote Link to comment Share on other sites More sharing options...
Tony Posted April 9, 2009 Report Share Posted April 9, 2009 Yep, yep and yep...... Their a bugger to fit, high maintenance and make the car real crashy so think hard before fitting them. Quote Link to comment Share on other sites More sharing options...
TarkMalbot Posted April 10, 2009 Author Report Share Posted April 10, 2009 Make the car feel Crashy? And High maintenance? Don't think I will bother! lol Quote Link to comment Share on other sites More sharing options...
Rich Posted April 11, 2009 Report Share Posted April 11, 2009 I thought poly bushes help firm the car up so why do they make it crashy? Does this only apply to the MX5? Quote Link to comment Share on other sites More sharing options...
Bazza Posted April 11, 2009 Report Share Posted April 11, 2009 i believe Tony means hard and uncompromising when he says "crashy" the original bushes are rubber, and quite soft so allow absorbtion of vibrations and flex where as poly bushes are quite rigid and tend to transfer all vibrations directly to what they are joining together it is a hard choice, the fitting of them will greatly improve the cars handling but they also compromise the cars comfort level Quote Link to comment Share on other sites More sharing options...

I've a feeling the squeak on mine in coming from the anti roll bar poly bush The MX5 is no family car though so if it was me I'd be tempted to fit them. Especially with all the other mods fitted to it. Quote Link to comment Share on other sites More sharing options...
Tony Posted April 11, 2009 Report Share Posted April 11, 2009 Cheers bazza, you said exactly what my brain thought but my fingers denied. @ER.... within no time they squeak and moan.... A bit like the wife when she wants you to visit the mother-in-law Quote Link to comment Share on other sites More sharing options...

A bit like the wife when she wants you to visit the mother-in-law So what grease would you suggest to stop them squeaking? I sprayed them with WD40 quickly but it didn't work. I suppose I need to undo the clamp to get the grease in properly. Quote Link to comment Share on other sites More sharing options...
Tony Posted April 11, 2009 Report Share Posted April 11, 2009 Yep, there's a special grease you need to use.... WD40 just drys out. Quote Link to comment Share on other sites More sharing options...
Rich Posted April 12, 2009 Report Share Posted April 12, 2009 Yep, there's a special grease you need to use.... WD40 just drys out. Where can I get the grease from and would I have to undo the bracket? I suppose it's the same grease that would be used on the rear arm poly bushes?

Where can I get the grease from and would I have to undo the bracket? I suppose it's the same grease that would be used on the rear arm poly bushes? I'd be interested to know which grease it is too. I had an annoying squeak which Tony pinpointed as the bushes for my rear FM ARB. He undid the brackets, greased them up and it disappeared. Just starting to come back again, but only occasionally over sleeping policemen. Would save me the 130mile roundtrip if I can do it myself!

Tony Posted April 23, 2009 Report Share Posted April 23, 2009 I've spent some hours online researching this today and found it to be a repetitive question in many clubs.... I'll have to do some more research for a definitive answer. Quote Link to comment Share on other sites More sharing options...
hms Posted April 26, 2009 Report Share Posted April 26, 2009 The answers I found were: 1. White lithium grease. 2. Silicon grease. (Transparent stuff with no additives.) This stuff is available from Maplins and is branded Servisol.) What you don't want is something that affects rubber so WD40 is out, I'd also be concerned about spray greases due to the solvents used to make the grease sprayable. (Don't know if that is a valid concern!) h Quote Link to comment Share on other sites More sharing options...

You should also be able to get it from a Dive shop. It's used for lubricating 'O' rings in the regulator. h Quote Link to comment Share on other sites More sharing options...
