Suspension bushes
It would appear from recent posts that I have the incorrect bushes for my live axle car. (Lolocost Nylaspa- 'KIN ROCK HARD!)
I have been looking at various websites for replacement PU bushes (Powerflex etc).
The thing is they cost the earth. Approx £160 for wishbone & trailing arms!
Is there a cheaper alternative?
Cheers Paul

Buy them from Luego or MK , when i bought mine they were about £45 for a fullset of bushes and inner tubes.
As discussed in another thread you may only need to change the ones on the back axle.

Hi,
I'm in the same boat having bought the Lolocost wishbone kit although I only intend to change the bushes on the trailing links and panhard rod
and even then only at one end of each rod.
My question is, does anyone have dimensions for the MK, Luego or Stuart Taylor PU bushes? I need a bush to fit inside a 25mm internal diameter tube
with a crush tube to accept an M10 bolt.
Cheers,
Craig.

the bushes i bought from luego were £2 per joint without inserts and size wise are
o/a length 22mm
bit that pushes inside the wishbone 13 mm long and the o/d is 29mm the i/d is 19mm the o/d of the outside shoulder (the bit you see when its all
built up) is 35mm
hope this helps, oh by the way they arethe same size as i bought from stuart taylor about 5 years ago..

Thanks Viper, it looks like they are too large for my purposes. Here are the Dims of the Lolocost Nylaspa 'kin hard bushes:
Inner Diameter of tophat = 14mm
Outer Diameter of tophat (the bit which fits into the wishbone tube) = 25mm
Outer Diameter of tophat (the bit which stays outside the wishbone tube) = 30mm
Overall height of tophat = 20.8mm
Height of bit which fits inside tube = 17mm
Height of the 'rim' of the tophat = 3.8mm
Inside Diameter of crush tube = 10mm
Crush tube material is mild steel and is NOT finished at the ends. It comes in lengths of 46.1mm and must be machined down to about 44.5mm for use
with the wishbone eye tubes and Nylaspa bushes supplied by Lolocost.
If anyone knows of a PU bush with these dimensions (or close to them) then please let me know.
Cheers,
Craig.

The other option you may have is to fit rosejoints to the front end of the trailing arms. Rally design supply them relatively cheaply and also supply
inserts to weld into the tube tapped to fit the joints.You would just have to cut the ends off the existing trailing arms and weld the inserts in.
This is a modification I am planning on doing to my car once on the road.

Paul,
Yes, I have a Rallydesign catalogue here (aka. a Car and Car Conversions magazine) which I got for that very purpose. I'm a bit bewildered at
the different types of Rose Joint (or should I say spherical bearing...) and am not too sure which I need. I am guessing that a 1/2 inch bore with a
5/8 inch shank is probably about right but I think I might post a question on the forum here to see what people think. My other concern with this is
that they are expensive and apparently wear out quickly. I'd recommend getting the rubber boot kit to help them last a bit longer.
I'll look at this option again I think...
Cheers,
Craig.

I've got a similar problem unfortunately, the suspension i have on the car are all 'book' sizes, but i want to change to
'poly' type for racing. Having just received the details from 'europa' the price seems expensive to say the least !!. I have
also tried the likes of 'stuart taylor' , mk, luego, mac#1 and lolocost !
All either say they don't do them for std size suspension 'eyes' or don't do them at all !!
My options seam to be :-
1, pay through the nose for them from europa or similar.
2,cut off all 'eyes' on my suspension points and reweld on bigger eyes (may involve changing all suspension brackets on car as well.
3,get some made for myself.
I like the sound of the first as it's all been sorted by someone else, but its the cost. the only other route is the get it made myself. I know
a c n c shop ( I work above one) can't find out price t'ill nxt week.
Any further options would be VERY gratefully received !!

Having them made is probably your best option, as at least you'll know they'll fit, and they're easily made from a length of PU
hollow rod. Try and source stainless steel tube for the crush tubes first (roughly 2.5-3mm wall), which will then dictate the ID of the PU hollow rod.
Cheers, Rorty.

Different types of PU
Just ordered a length of PU from RS components (30mm bar 'Tufset' Rigid PU)
When I looked at its properties on the Rs site it stated that it has a shore hardness of 76.
On arrival this stuff appears even harder than the LOlocost originals
So it would appear that in this case anyway, the shore rating has nothing to do with the 'give' of the material
Any thoughts?

Paul,
I'm no expert but the fact that it is described as "Rigid" PU might be significant... 
On a more constructive subject, I was looking through the Rallydesign catalogue and there are dozens and dozens of different bushes for all the
various cars listed. Surely probability alone would suggest that one of these would fit. Does anyone know of a resource on the web where different
bushes for different cars are detailed with dimensions etc?
Cheers,
Craig.

I have looked at this material it is definitely to hard for suspension parts and actually quite brittle, I have made bushes out of it for other
applications but would not use it for suspension. It is harder than nylon and i would assume the shore rating is on a different scale to that used for
rubber but cannot remember for sure.It might be useful for making pedal bushes if you make your own pedal box , if not then maybe spacers or
insulating washers.
