started with this lovely S1 Elise:

and then these, wide arch S1 Exige body panels:


stripped everything out of Elise and sold that I didn't need - engine and box went to Switzerland!

Safety Devices roll cage ordered:


& fitted:


then a big suspension & brake refresh/upgrade:

all wishbones chemically cleaned and yellow zinc passivate coated, with 2 coats of clear PIR15 for extra protection
all new bushes & steering rack - new Nitron shocks


Front AP calipers onto rear, with Hi-Spek spot calipers:



AP Caparo 4 pot calipers on front:


larger bore master cylinder fitted:


wheels needed to be larger to fit wider arch clams - 50mm each side at rear and 20mm each side at front
so went with Braid (not the lightest, but look right (I think) - 17 x 8 front and 18 x 10 rear:

fitted with Toyo R888R tyres:

body work took ages to get right - many months work:

Looks like a great project.

Don’t know what power it’ll have, but the brakes will definitely be up to the job!

Saw the finished car earlier, I am glad you did a thread....will be watching this one.

Great spec and looks lovely, I bet it is shockingly quick on track?

whilst engine was away, bulkhead was prepared and larger Pro Alloy fuel tank fitted:



then soundproofed and heat shielded:



with oil, water and charge-cooler tanks fitted & Laminova


these pics gives some idea of difference between clams:



had always planned for car to be painted Porsche Miami Blue, I think it looks good,
great paint job by Anthony:



panel build up:



body re-build almost finished:



clams have since been removed for lights, wiring, mesh fitting:


ally panels are a quick release system to slide rear clam off rails bolted to longerons

whilst clam of, car went off for exhaust system fabrication and fitting - to ZK Engineering in North Yorks - great job:




this is about where I'm up to currently, not finished but should be for next spring.

Bloody hell

I had a ride in an Audi powered mk1 with about 300bhp and that thing could *move*.

This looks significantly more potent.

Good colour too

Looks awesome!!
Mini LeMans car.
I think I've got the same Braid wheels on my Ultima.
They look ace in gold.

I would agree with the last post...

That engine and suspension etc in the original classic Elise S1 would be amazing...but then I used to have a classic Elan S4SE so may be a little biased.

Fascinating though to see the work involved in this project, and it will be an amazing car when finished!
