Rear anti roll bar

Hello everyone!

I am looking to buy a 22mm rear anti roll bar. I have found this one from Whiteline, though it doesn't say it fits the Fiat Coupe. Is it compatible?

I want to follow Nigels advice and go for the 22mm rear arb. If I can't find one, will a 23mm one be alright?
Not really looking forward to making a track car out of this. I will take it to my local track, but it won't be something I will do on a regular basis.

The 23mm one I found is from Ultra Racing. Is it allright ?

I have the 23mm one from Ultra Racing, and is a good alternative to the standard 19mm offering that came with the car.

However the brackets they supply for the 23mm bar were oversized, so I had to install some packers to make the bar be correctly clamped

See my restoration thread for further details

i too have just ordered a UR 23mm bar, mainly on Jamies recommendation. also due to them being <£200 here in the UK,

update for ARB

ID-Workz messaged me yesterday (after ordering last saturday) informing that theres upto a 4wk lead time from UR > ID-Workz. for me not a deal breaker, as ive ordered in plenty of time. but be prepared for a wait if you want it quickly
