250 Anti-roll bar diameter?

Discussion in 'Suspension, Brakes, Wheels & Tyres section' started by jack250, Jan 4, 2018.

  1. I've found the info for a 265 cup (24.2mm) but can't find the info for the 250 cup. I presume its the same as the 265 but don't want to order the wrong stuff. Does anyone know for sure?

  2. And has anyone changed these themselves? Easy/hard?

    Cheers again

    Cup spec ARB is only 22mm, the superpro arb is 24mm

    Non Cup is 20mm

    I don't think they changed the thickness between the model iterations on the MK3 as I have a pair of bushes on mine that came off a friend's 265 facelift and they fitted

  4. Cheers Jamie. Are you still running standard arb/arb bushes? I was considering upgrading as mine are shot...Superpro or powerflex maybe.

    Did you do the work yourself mate?

    Superpro rear arb at the moment but have the front one to go on as well, fronts a pita as the subframe needs dropped so I'll pay someone to do it.

    Have black powerflex on the stock arb though
  6. Does the subframe need to be dropped just to loosen the bolts for the arb and fit the new bushings? I was thinking it could be done while the arb is still in place?
  7. Sorry didn’t read your q properly!
  8. what will be diameter of the rear ARB for Cup 250? Thanks
  9. Post further up this thread says 22mm.

    They don't have a rear arb.
  11. So that if i installed the supro anti-roll bar (18mm) at the rear only. It could reduce understeer theoracrically?

    In theory, yes.
    In reality it does very little though.
  13. How about the front SuperPro 24mm sway bar? I would combine it with their sway bar link kit.

    Have thicker ARB from Clio Cup Racer (20->22mm) on my Clio and it made a noticeable difference.
