1995 Crossflow live axle rear offset required

[Temple Cloud]

I'm changing (hopefully) from 6" to 7" rear 13" (95.25 PCD) wheels but need to know what the offset is. I've been told it probably is ET24 but wondered if anyone knows if this holds for this aged Crossflow with a live axle.

I've been told how to measure it but thought I'd ask the forum first to circumvent me removing wheels etc

Thanks in advance

Mine are ET12 with a couple of ET19.

Thanks. It just gets clearer and clearer

I'd check the backspace / clearance. As said Caterham spec'd 19mm inset (negative offset) for 6" rims on live axle cars.  However in changing to 7" rims with the same offset you'll increases the backspace by 1/2". The suggestion to use an ET 24 rim is probably to reduce this and give some of the clearance back but would increase the track marginally more.

Incidentally why use 7"? That puts a lot of tyre on the road, assuming you'll be using 205s, and probably not good for F/R balance
