Budget Scimitar 4 pot caliper and vented disc conversion for a V8 Se5…

SE5 / SE6 compatibility: Scimitar SE5 and SE6 hubs are (I believe) similar so this should work on either variant, it just happens it got submitted under SE5 🙂

Ed Reid of New Zealand is working on fitting Peugeot 505 ventilated discs to his Scimitar SE5a. The car is undergoing a full body off rebuild and Rover V8 conversion so we hope to see it soon on the More V8 Scimitars pages…

Ed wrote “…here are a couple of shots of the work so far. Now I’m waiting to get some 4-pot calipers as fitted to 2 litre Austin Princessess and, I believe, some Jags. These are a straight swop for the standard Scimmy ones. As you can see I have used the standard caliper in the photo, needs a little machining and a 4mm packing piece, but nothing much.

“I’m going to get the packers laser cut so I could e-mail the drawing to you or even get a few extra ones made and post them if anyone was interested.”

…Yes please Ed! Hopefully once complete we can make this available as a .pdf download for anyone else wishing to make the modification.

Simple drilled / grooved upgrade

Tom Follows has upgraded his SE5a brakes with drilled and grooved items from TR Revington. He wrote “They are standard (refurbished) calipers with disks supplied by TR Revington, the disks were £100+Vat and fit straight on. Braking is improved (certainly from my old worn out ones) and look pretty Bling through the wolfraces!!!!”

SE6 owners

Try this out as I believe the hubs are the same, or, try the Wilwood conversion. It’ll cost more but you get superlite calipers and a slightly larger disc.

Scimitar Rear Disc Conversion

I’ve had a 3.77:1 Jag Powerlok diff fitted inside a 4ha axle and have now completed my Scimitar rear disc conversion.

Even when you’re not thrashing it, with more power you end up braking from much higher speeds than with a standard engine. Scimitar brakes leave you wondering if it would help to just maybe stick your feet through a hole in the floor like the Anthill Mob.

I know, I know “Scimitar brakes are more than adequate” say all the purists. But face it, bigger vented discs and 4 pot calipers at the front are just GOING TO BE BETTER … … Stop whining about how great a well rebuilt set of standard brakes are OK!

The kit uses Wilwood 4 pot calipers (very light) and Nigel at Queensberry Road Garage (01536 513351) does them including EBC vented discs & pads, braided hoses plus all the bits and pieces to fit for about £600 – £700. Some say pricey, I say it saves time and mistakes – DO IT! Sorry about the rust, when I fitted them 2 months ago all I wanted to do was try them out so they got used before pictured.

Oh yeah, and they fit neatly inside std 14″ wheels too…

Try out Ed Reid’s scimitar SE5a brake conversion using Pricess calipers and a Peugeot 505 vented disc. I think SE5/6 hubs are the same so it should work…

Scimitar Rear Disc Conversion

I’m working on a spare 4ha axle to make a Scimitar rear disc conversion.

UPDATED:
Scimitar Rear Disc Conversion…

Scimitar rear disc brake conversion. With 4 pot Wilwoods up front, and a lighter engine you need something a bit more up to the job for the rear…

LATEST (Sept 23rd ’05): My spare 4HA axle is ready to fit to the Scimitar. It features Honda Legend (Rover 800) rear discs, Audi 80 38mm rear brake calipers and a 3.77:1 Jaguar Powerlok diff.

There will be another update once fitted and tested…

Since no-one else volunteered any information this conversion was worked out by myself and ABC Computer Desks (yes, they make desks but as engineers were invaluable in getting parts designed and punched!). Its very “trial and error” and will require set-up via an adjustable brake bias valve to get proper braking balance right.

the handbrake won’t be an issue, the mechanism on the VW / Audi calipers looks very Scim-cable friendly… Though I do plan on having an hydraulic handbrake too for improved, er, manouverability 😉

Other Options…

Jaguar IRS axle – An article by a Mr Will Cowell who converted a Scimitar some years ago to Jag IRS.

There’s some debate (as usual) about the benefits of Jag IRS but here we’re all in favour of modifying and trying rather than whining and being negative.

People worry about “unbalancing the braking effort”, one guy I asked bored me to tears about “asking the RIGHT questions”, “what is the un-sprung weight?”, “have you calculated your…” – you get the picture! It’s all crap, if you just want to go a bit quick then get on with this mod, if you have the time then do the maths and impress girls with your superior speccy powers!

Disclaimer: I do not recommend this to anyone OK! Messing with brakes on a car is very likely to get you and others killed nastily and unfairly – don’t do it!!!

Watch this space to see how I get on though eh…

LSD into a Scimitar GTE…

Another job in the pipeline… Along with the rear disc conversion is the fitment of a Jag LSD, lots of people have done this in Scimitars and its pretty strightforward. To keep things simple do what I’m going to do, go to Nicol in Kidderminster and ask them to dismantle your old axle and fit the Jag LSD or Powerlok of your choice (i.e. what ratio do you want?). The internals of one of those massive Jag IRS setups found in the back of many a Jag XJ / XJS etc will fit inside the case of a Scimitar 4ha axle with only minor machining of custom bits – easy eh…

Again, photos etc when done, although what with being impatient and all you’re not likely to see the work in progress, just a nice juicy two-wheel burnout.
