Have you checked with the usual Lotus specialists? I know PNM sell them.
FWIW they rear calipers are the same as the Lotus Elise (but have to use Elise pads).
I wonder if the rotors are the same with a different bolt pattern. IF (big if) they are the same (off set and hub diameter) there is a fellow selling a used set of fancy two piece rear rotors on the parts forum. They could fairly easily be re-drilled to the Esprit bolt pattern I would guess. Might be better to experiment with some used stock elise rear rotors and see if they fit.
Pretty sure they will because it looks like PNM sells the elise rotors re drilled for an esprit, they are slightly thicker, again so you have to use the Elise pads which are thinner.
I have not tried it so proceed with caution, however several folks have put the elise rotors and pads on the Esprit I am pretty sure.
SOLD 4 new outer rings and related hat & bobbin hardware. Based on the expert guidance from LT family, I bought these in anticipation of needing to do a brake job on my 2003 Esprit. Never did the track event to warrant a brake job and the car is now sold. $750 for everything + shipping. The...
Thanks for that link Molez but yes they're a different setup on the 96-97 - they look a lot more basic (traditional).
I'll see if I can get these machined. With the ongoing covid crisis it may take months to get new ones unfortunately.
During this virus period, I've had 3 packages with spares from SJ with just 3 days in transition. I spoke to Steve recently, and he confirmed that they are real busy, but stil managing to ship almost on the fly. So it appears no worries there.
I managed to get these machined above min thickness so I'm good. Below are some some measurements I took before mounting them. It looks like if somebody is in a jam for rear Brembo vented rotors the Jaguar/Ford units are close enough and should do the job - not sure though. Textar 92109603 or Zimmermann 250.1344.20 for example.
My next question is how the heck do you bleed the brakes on these cars? I connected a Motive Power Bleeder and the car didn't even know it was there. 1997 with the Kelsey Hayes unit.
I did a search on 300mm rotors and compared dimensions to find the similar rotors. If there's still an issue with shipping or a backorder I'll try the Ford/Jaguar units next time. The rear brake setup on the early V8s look like a parts bin special considering the rear rotors are actually larger than the fronts and the pad contact area is only about 2/3rds of the surface.
