Another Polybush question...

[MarkF]

Hi guys,

I am looking to buy a full set of polybushes for my 1987 320i. The car is a drift car so mainly track use. I have a few questions i hope someone can help me with!

-Can anyone tell me if eccentric bushes will be of any benefit to me with what i do with the car, or shall i stay with concentric?

-Does anyone know the diameter of my front anti roll bar so i can order the correct kit! Im assuming other than ARB diameters 320 and 325 kits are the same?

- My 320 has 325 rear trailing arms (discs), are these the same bushes?

Cheers, Mark

Guessing you mean the front wish bone bushes? Eccentric bushes give a greater caster angle at full lock so I would imagine that would be a benefit for drifting.

Only way to tell what size arb is to get under the car and measure it, either with vernier gauge/calipers or a adjustable spanner.

All trailing arm bushes are the same.

Thank you for the above! Will measue the ARB, at the time i posted this i wasnt near the car (didnt want anyone to think i was being lazy!)

Cheers, Mark

320 didn't come with a rear ARB as standard, front one will be 18.5mm if it hasn't been upgraded.

I'd recommend fitting a rear ARB if you do find you don't have one, can really feel the stability and will make drifts more progressive.

Go for an eibach or ultra racing arb kit. They will fit very well and come with the polly's. I went from eccentric back to standered. It is worth doing the diff and the rear beam with powerflex polly's if your a drifter.

Hope thathelp's fella.
