Love the look of the wheels on your car, did you use spacers since on the car - I am interested in fitting a set to my E85.

No spacers at all. Just the wheels as supplied . Not clued up on offsets and the like, so relied on Chris at Elite to just get it right for me and they fit the arches really well.

Photos before I fitted Eibach springs. Excuse my mate looking simple . On our way to Gurston Down Hill Climb Championships last year.

Sorry, just double-checking – are those Riva DTM 18s?

Thanks for these photos, super helpful as I have just had a quote from Elite

Still toying with 18 vs 19

From the photos it looks like on the 18s you definitely would benefit form lowering and I note you say these photos are before you lowered on Eibachs

and I was looking at lowering too, but then I read something yesterday that suggested switching to eibachs would be a bad idea?! so now I am in 2 minds

18 inch Rivas + Eibach Springs
OR
19 Inch Rivas with no springs

Also I cant quite tell from the photos but how deep is the concave on the rear?

Thanks so much really appreciate the photos etc

There is virtually no difference in 18 to 19's with wheel arch clearance , as you are just taking the rubber off the tyre sidewall and making the rims larger diameter. The rolling radius stays the same otherwise the speedo wont read correct.
I have M suspension on the car and being the usual rear spring had snapped , decided on the Eibachs. Yes, there is a drop and its not an everyday car , so just careful when I drive it. Made the car more supple and not hit the inner wheel arch liners yet , even after driving in Oxfordshire !!
I will be swopping to B4's Bilstein at some point , so perhaps consider the shock and spring kit , if funds allow for your car. They are getting on a bit these days. As to if I get them before we venture up the NC500 this year , not sure, but they are less 'bobbing' than standard springs . Make sure you get a geometry done afterwards too. Mine was all over the place and a lot more planted now.
Sorted my hosting now, so this is it after lowering and a 1000 miles on it to settle in.

It will feel better on 18s. (Even better on 17s, but that’s not one of your suggestions).

Even though I love the look of the coupe with 19" CSLs (don't look as good on the roadster), I went from 19" genuine CSL, to 18" 224M (OE) as I thought the combination of standard suspension and the 19" wheels made the ride & handling completely unacceptable.

19" CSLs on standard suspension (don't seem to have any 'clean' picture of these)


18" 224M on standard suspension


18" 224M on slightly lowered B16/PSS10

Not sure the standard brakes will fit under 17s. Even 18s are close.
