Hi Mark.

Here's a thread on the rear discs....

Although the S1 is discussed, the rear discs are the same as your '83 S3 NA.

Hope it helps.

From S&J's website...

REAR BRAKE DISC (Non-Lotus) (1976 - 1984) SJ079J0031 EACH 62.00

That's a bit better!!

[mark p]

Thanks for that john.
I rang powerstop and talked to a helpfull guy called martin and he told me that they wont have any discs in until the later part of this year.But the good news is that the solid rear disks will be £45.00 + vat and the solid with grooves will be £60 to £65 + vat and he will keep me informed when they wiil be in stock.

Hey Mark....just flog those rusty old bits of scrap you had off my car on ebay and use the proceeds to subsidise some proper kit now instead of next winter! No sense in being dangerous or off the road for a whole season.

[wayneb911]

So where these really lotus specific discs? Surely there must be something out there the same. Very early BMW perhaps. What about the Citreon SM or was that just gearbox? Maserati Merak? Same pattern maybe??

[Bibs]

Have you tried a Lotus dealer?

[slewthy]

"OEM" on ebay at mo for £200. Seems quite steep.

Supplier has discs for 85onwards for same price, yet there are some of these for just £70ish (pair) from other sellers. Worth asking if they have any pre 1985 discs?

Hey Mike if I can sell them I will give you the money mate

Hi, I have been looking for the same discs for about a year now with no luck.

Steve

[rlc]

Just tried to get them from Steve at SJ's . He's just emailed back to say none from Lotus and his non-lotus supplier is not cooperating.
So if anyone has any solutions.........????

[Steve Type 085]

Hi, I have had rear discs on order with Steve at SJ for 53 weeks now. In that time I done lots of looking. On the website http://www.espritfac...e.com/xref.html it states that there off the front of a 1984 Renault Le car (which I think had only three wheel studs untill 1985) I have not been able to find any size or thickness of these disc and any that has them. (note the site states: Unless otherwise noted, this applies to a 1989 Non-SE Esprit Turbo. In Australia all pre SE had inbound brakes the same as S3, they were just S3 with the steven's body).

Happy hunting

Steve

Steve,
I fished this info from the turbo esprit forum on Yahoo Groups...

> Re: 83 Turbo Esprit rear rotors


You are right about the bolt pattern. After I sent this message I
remembered that the rears had had 3 bolt pattern....

BTW measuring Le Car rim I have in my garage... I measured
approximately 4.75" spacing between mounting holes. What is the hole
spacing on the Lotus rotors?

I do not belive that the rotor is from Le Car due to it's large
diameter... Would it make more sense that rotors were from the
Citroen DS21 or SM which used the same transmission? You would only
need to change brake calipers to a model which had hand brake
function build-in... like Alfa Romeo GTV6s...

Here are your choices of cars with inboard brake...from Wikipedia:

* Alfa Romeo Alfasud Alfetta GTV GTV6 Giulietta 75 90 SZ Milano
* British Racing Motors: Some BRM racing cars had a single inboard
disk brake, acting on both back wheels.
* Citroën 2CV
* Citroën DS
* Citroën GS
* Citroën SM
* Jaguar E-Type
* Jaguar XJ (until XJ40)
* Jaguar XJ-S
* Hummer H1
* Lancia Aurelia
* Lotus 72 Formula One racing car
* Lotus Elite, Elan, Esprit
* Mercedes-Benz W196 and 300SLR
* Rover P6
* Subaru G
* NSU Ro80 <

and then ...............

Re: [turboesprit] Re: 83 Turbo Esprit rear rotors

I checked the dimensions of the Renault LeCar and have found the overall
diameter to be 228mm while the stock Lotus piece is 275mm so that won't work.
Somewhere found the Yugo mentioned but that has an overall diameter of only
227mm. The Toyota Celica with the correct thickness of 10 mm is only 228.5 in
diameter and finally the Jaguar fronts have a diameter of 284 and a thickness of
24.2mm I checked the Jag rears and found the diameter to be 278mm only 3mm over
and 10mm thick same as Lotus but the offset is 67.8mm rather than the 30.48mm of
Lotus. The total offset of 30.48 might be a bit off as I was measuring my old
parts for this dimension.

The conclusion is I can find one or maybe two of the dimensions but never all
three regardless of the hole pattern -so if you find new ones at a good price
buy them!

If you ever need rotor dimensions check Brembo.com as they have great info on a
lot of models.

If you can find the dimensions of thickness (when new or minimum), overall diameter and the overall width (when mounted) or height(when laid flat ) that would give you enough to find an equivalent and then just have the 3 holes bored out. as it's sandwiched the additional holes shouldn't matter as long as the holes are bored in such a way as to not make it uneven.

[Paul Coleman]

I spoke to Mike at Fibreglass Services about 4 or 5 months ago and he was going to have them remade at that time. I don't know whether he ever did or not as I've not spoken to him since but I have the same problem - I need a pair and couldn't find them anywhere.

Brembo's site has a great search engine but couldnt come up with anything close sadly. I even thought of Wilwood rotors and have the aluminium bells machined but they dont seem to have the thickness
A group buy sounds like a plan if you can find a manufacturer

[andydclements]

Wilwood appear to aim at the high braking performance end, so vented stuff, we just need solid.
when you checked Brembo's site did you consider centre bore and number of holes don't matter. Even overall size doesn't as you could get larger and have them turned down.

[rlc]

Hi Andy.

This is the search link:

http://www.brembo.co...T=NoModifyGuest

...based on the offset( or thickness A in Brembo terms)...doesn't seem to be any that fit the bill

Rob

[andydclements]

Can't tell by the link what dimensions you searched under but do you mean there is nothing with the correct offset, irrespective of other specs?
