That’s exactly what we do to fit vented discs on the SS1 etc - spacers and an extra set of o-rings with longer bolts and the metro turbo fitting kit (they had vented as standard).

Are you happy with your New set Jim?.
Pictures please?
Rest of the parts are in transit.

Does it work with Lockheed callipers though?

they bolt together so no reason why not, but the vented discs will only improve the car if your giving it hell

Easiest and cheapest upgrade is Drilled and Grooved disc. :idea:
Readily available, I think I have a few sets left from the last batch I sourced.
Mick G has them on his Middlebridge along with 3 pot Girlings, which use a bigger pad, and has used them in anger at motorway speeds :o

I have vented wilwoods with dual circuit remote servo that will cope with anything I have done.
The most important factor is pad make and material, get the heat range for a particular use.

I think uprated brakes are essential if I fit the ethanol engine, I've also got a Kent fast road cam for it so, not only will the emissions be much better ethanol is carbon negative

For a road car I don’t think updated brakes are essential at all - BHP doesn’t determine braking requirements, it’s how you’re using it. The small sports brakes are known for fade after heavy use on track (or mountain passes :D ) - the GTE brakes are pretty good as standard and simply fitting vented won’t improve the braking power, just the heat dissipation.

Put simply,

For more braking power, fit larger diameter discs/larger area pads

For more braking endurance (ie heat dissipation) fit vented discs.

ethanol is carbon negative
If you ignore any CO2 produced during the creation of ethanol, it can be considered carbon negative until it is burnt when it becomes carbon neutral as you're then producing the same level of CO2 as that absorbed by the plant from which it is made. Still better than petrol, of course.

In truth, the only truly carbon neutral fuels are wind, solar, tidal and wave as no CO2 conversion or emission is involved whatsoever.
A wave-powered Scimitar, now there's a thought! :)

You can’t ignore co2 produced during creation though (or impact on global economies from changing farming practices)

And none of those fuels are carbon neutral (at point of use) once you’ve built the machines to collect, convert, transfer and store it :P

Great Link!

You're right, of course, Jim. I was trying to make the point that most carbon neutral/negative claims are very dubious. :wink:

However, wind, solar, tidal and wave are carbon neutral in their natural state, it's when us humans get involved that things are spoilt!

I still fancy a wave-powered Scimitar. Must be better than a coal-powered Crapi. Fancy a challenge? 😄

Isn’t petrol carbon neutral in its natural state? :D

I fancy an electric Scimitar but that has some of the worst carbon footprint claims of all alternative fuels :P

As unextracted crude oil, yes. However, once it's been refined ..... :-P

Anyway, I'll stick to my ancient, polluting, petrol-powered, torquey Essex for my Scimitar kick. My eco-nod is my hybrid daily (no, not a Prius!), the battery of which produces far more CO2 during manufacture/recycling than the hybrid technology will ever save! :doh:
