Does anyone recognise these?

They are 6x15 with a 41mm offset, I am using a capri axle and cortina front, can anyone forsee any problems with using this much offset?They have a 2.5 centres which is spot on. Rescued attachment DCP_0363sml.jpg

Looky likey Mk5 Escort RS 2000 to me.
As for the wheel offset, there may br probs....there may not. If the wheels clear chassis, suspension, brakes etc, they *should* be OK, but the offset can play a major part in suspension geometry, especially on the front end.

The only thing I know from (limited) experience is that you can't tell exactly without trying them (unless you're very good at technical drawing and comlicated sums).

On my Robin Hood with all standard single donor Sierra setup and wheels I had interference between (I think) the cycle wings and the anti-roll bar (or some other susp bit) at full suspension travel. All to do with the slightly different travel compared with the Sierra strut arrangement - and the Sierra not having cycle wings!

To save wasting too much time, find out what the off set is of the wheels that were mounted to your front hubs/uprights originally.
If the off set differs from the new (RS2000 ?) wheels by more than 2-3mm, forget them, as they will mess up the scrub radius.
If they work out within tolerance, then the next thing to check is caliper/steering arm clearance. The easiest way to do this, is to bolt one of the new wheels on a front hub, and see if it rotates without interferance.
Just check for clearance on the rear axle too, and if all's clear, they should be OK, but also bear in mind the cycle wings/rear arches.


P.S. I'm asuming you'll be using the same height of tyre as originally fitted to the front wheels.

The original offset I think should be 19mm for a Mk5 Cortina. I dont understand scrub radius, I would have thought that using home made wishbones and not uncle Henry's would alter the geometry of the original Cortina uprights. I am looking into spacers to correct for the other 22mm of offset, any ideas for a reasonable supplier?

if u look at my car ull see that the wheels stick out a lot

i am also using a capri diff and cortina fronts (i think)

they are mim alloys with a big offset

not sure what the offset was

ive sold these now cos i would have had to buy buy wider mk style arches

Mark, before you bolt anything other than the standard wheels onto the front uprights, you should get your mind around the definition of scrub radius. It is extremely important to not only how the steering feels, but also how the car handles.
Try a search for scrub radius, or have a look at the Tech Page on my site where there are also a few diagrams.

Read and understood, looks like I will have to keep on looking for wheels, I have a set of original rostyles for now which have ET19 offset, which, as far as I can tell is just right.
Should be able to sell the RS2000 wheels for what I paid for them!
Thanks,
Mark

I should have mentioned, fitting tyres with different aspect ratios will also affect the scrub radius.
If your wheels of choice are close to the correct scrub radius, you may be able to fine tune them with different tyres.
