The polybushes general thread

Recommended Posts

Hello folks!

Have searched some keywords, but can't find a satisfying note about.

The questions are: What are the main differences between the red-Lotus and the aftermarket "yellow"-ones ?

Is it only the colour or *one-piece* vs. *two-piece* shape, or the costs , or the availability, or what ever ?

Marcus calls "his" bushings "...very soft.." on his personal dealer page. So is it real that the Lotus version is stiffer?

Some said in an other treat it is a no go if you want to change the "arb"-bushings, but who offers this if i want do it?

(or are these arb-bushings included in the Lotus- / PUK main kit?)

Re the ARB ones, many people have said the poly versions give a lot of under-steer, so people seem to keep away from those.

The colour isn't the only differentiation, but it is a good way to spot they're not rubber, and spot which kit has been used. The reality is that any one of the kits out there might be the one that give the amount of feedback you want, but the Lotus ones are designed (at length) to give the same ride as the car was originally designed to have. The Lotus ones are not the same rigidity as the current Lotus rubber bushes, that's why the developed them. the current rubber ones have different characteristics to the original design specifications due to changes in rubber compound (for the worse).

If you want a car that handles as the factory designed it to handle, then Lotus bushes.

If you want a softer feel or a harder feel, then discuss with the other suppliers.

what i meant was: is the red [Lotus] plastic a stiffer structure than the yellow [PUK/R&B] version ?

(My car is 10years old now, and i want to go on track more often )

It is probably best to ask Marcus, he's probably compared them, most people will not have driven the same car with both kits in, so it's difficult to do a like for like comparison.

If anything the Lotus ones were softer as I recall.

Marcus's ones are (sorry Lotus) better imo, as they are 150x easier to fit !

Really happy with mine, I have them on both the cars.

Absolutely! 2 piece are the way to go.

I couldnt tell you the difference as my originals were completely shot.

My concern was not about changing the ride quality but rather finding a solution that would be longer lasting that the original.

*two-piece* vs. *one-piece* is not the problem. I can use hydraulic tools from Truck-Service ... B)

But who has developed "arb" bushings also ?

Jonathan, so what did you have really -purple or the yellow ones ??

Can't find a functional *Parts* page on PNM Lotus, does SJ have those section?

And does anyone have an information about the costs? I have only the (around 400 )-Euro information for the yellow version. What is with the red Lotus bushings?

Update: have seen the red on SJ-sportscars: around 190 Euros for a Set of rear ones (without Tax!)

And around 45Euros for a front-end Set . The fronts are only for a top link, were is the rest? And those front bushings are black colored ?!

Marcus, i know you want to kidding me :lol:

I have some pieces of wood from our forrest...

Around 400 Euros(incl. German tax!) is not the problem, but to compare them right, i need all informations . And if i buy the parts from SJ-sportscars i have to add the tax rate ! With Tax the 190 Euros is near to 200 , and that only for *rear set*

What i now have to find is the price for a complete SJ-sportscars *front setup*

So i can go in the end with the yellow 'R&B' set-up in front and rear, and of course some red from 'SJ-sportscars' for "antirollbar" in the front!

Please ,can an moderator compress the treat . So that we all have only technical facts, part-numbers and prices in here... .

(it does better suit the title of the treat :lol: )

I made my own for the rear. Haven't looked into the front yet. I don't remember the durometer I used but I can look it up if anyone is interested.

the refit was easy, compared with the old . All i need now is new locking nuts for the lower stud.

Later (if I've got my new certification) i can easily unscrew all parts (as now all is fitted with fresh copper grease) and get them powder coated.

but it looks not elegant, as long as nothing is sand blasted and powder coated ! Was just the way to go, for the immediate road certification. I need the rest of the time until the month is gone for the refitment of the turbos, front brakes -and maybe an fit of 'new-used' (not much used ...) shocks front and rear.

And yes -there was an examination in the way to come ;-)

PS. is good to see how tight the bushes look, no more difference of the joint eyes in alignment to the lock screws. Hope it will have this straight orientation for more than the next 10 years (as that was the time the originals last, but those were gone really fast in the end. Car moved from side to side and had some 'self steering' under hard braking from German Motorway speeds to sero... )
