Please find attached a disc bell drawing for a 11.25" rotor, Wilwood part number 160-3846. This disc bell is for a Granada hub, but it might help you get something down on paper that you can then modify. This kit uses the Wilwood narrow Superlite 6 pot caliper. If you look on the Wilwood...

Hi Stuadh, I produced a spreadsheet build template, the idea was to list everything that goes into a typical build and use this for two purposes. Firstly adding costs against it gives you a good estimate of the likely build costs and secondly it allows you to focus on what parts you need to...

You never tell the sound tester the true max RPM for this exact reason. I've been race engineering a motorbike engined sportscar this season and at times we've had to tell the the max was 4,000 rpm off the limit to squeeze in under the limit. But interestingly what was causing the problem was...

Ron, I'd call Penske Racing Shocks as they will almost certainly have something to do the job. D.

Hi Geoff, According to the Unbrako technical data you are looking at 326 inch-lbs torque or 37 Nm in new money. http://www.unbrako.com/docs/engguide.pdf its very useful for fastener selection. D.

Two way adjustable gas mono shocks like the Nitrons etc, have low speed adjusters. This is damper shaft speed not car speed, low damper shaft speeds are what you feel during all your transient movements like turn in, power on, braking etc. So you can make the car feel considerably less twitchy...

Multiple reasons that i sell aluminium shocks only:- 1. Steel bodied cheap shocks like the Gaz, Spax etc don't tend to last long before rust is present and this looks bad and also siezes up the threads. 2. Weight 3. Heat transfer. Shocks worked hard produce a lot of heat and you need to...

Professional Motorsport Parts, Spares & Rally Equipment from Rally Design

Hi Rene, The kit price is £440 for the 4 shocks and the 4 springs. + VAT and delivery (£25). That's for all aluminium single adjustable shocks, or +£300 for the double adjustable version. D.

Hi Rene, Pic is of the shock kits i sell. The sizes you provided work perfectly. The rear shocks at 420 full open will give you a stroke of 140mm and the fronts will allow a stroke of 110mm. It is usually the shock that restricts the droop travel of the suspension so that is perfectly OK...

Hi Rene, If you can tell me the overall length of your shock absorbers, at full droop and at ride height and if possible at full bump (where floor would hit the ground) i can help you specifiy them. I'm just CAD modelling my shock kit at the moment i can send that over if it helps. D.

Lovely looking rear end! Where did you get it? D.

New seat just back from the upholsterer.

Hi Andy, Good skills, door bits look ace. I got my prototype seat back from the trimmers today. It's your seat shell design trimmed with Alcantara centre and leather look vinyl sides. I'm really pleased with how it's come out. How are you getting on with yours?

Update on the Ally uprights. These were originally made by Raceleda, with fabricated steering arms. All of the failures known/recorded were with the Raceleda items. Rally Design report no failures of their ally upright, but, due to number of steering arm failures recorded on Raceleda...

Hi Andy, Any comment on the front upright issue? Perhaps you missed the questions posed by a few people on the previous page of the thread. Kind regards, D

The aluminium uprights they sell are lovely little items, but, the manufacture of them is really uneasy about them being used on GT40's says they are just not upto the job. I'd love some feedback on them as they are super cheap (£195 retail) and i wanted to use them myself, but with reports...

A typical Powerlite Handbrake kit retail from Rally Design is £354.50 + pads (approx. £25-£50). That includes calipers, discs, mounting brackets, nuts/bolts and development costs etc.

Trev, PM Sent The picture shows Powerlite handbrake calipers for the rear. This is highly unadvised by Wilwood and Rally Design themselves! The catalogue states they are not suitable for cars over 750 kg's. By the looks of things the front calipers are Midilites, if so the brackets for the...

I guess it's fair to say that the Type as is perhaps the least loved 40 replica. I've priced my kits so you can build a nice one from scratch with a 302 and Audi box etc for under £20k. D
