I prefer the 'feel' of 6+6 - the car seems a bit more communicative and I have the confidence to press on. thats on track with 220bhp, on the road I cant tell much difference. . I went to 6+8 as the 13" *6 looked lost in the rear arch. I wouldnt say theres any more grip from 8" rears - if you keep the tyre pressures the same, then the contact patch will be the same, just a slightly different shape.

Is it easy DIY - I'd say yes having done mine earlier this year after one started leaking. Seal kit is ~£20 and includes new bleed screws. Dont need any special tools- just try and pump the pistons as far out as you can ( not all the way out- just enough to get a decent grip on to pull the pistons out - they need a good tug )whilst brakes are still attached to car- or use an air compressor.

I think they are M8

Hi, swapping gearbox on my duratec I took the clutch cover off to measure clutch plate (AP 5352) wear, but the build manual doesnt mention the torque for these bolts. Anybody know what they should be? thanks

I had to replace 2 of the original BMW diff cages. 2011 car. since I got the upgraded back plate version its been fine. took the diff out to do it. I dont know if there is enough movement on the half shafts to let you do it in situ. Adam

Another vote for talking to simon, or at least someone who knows 7 suspension. I had harder springs put on the front of mine by a suspension expert. It did make it tighter on track, but it was skittish and harsh on the road. Also i ended up removing the front anti-roll bar completely as it was just understeering too much with the stiff springs. I have changed to slightly harder than normal spring , with adjustable dampers. the car is far more compliant on the road and can now fide potholes without it feeling like the end of the world. If you firm the damping up, the car feels really taught on track - much firmer than with the stiff springs/normal damper. Adam

Yes, I bought some rear wings from them last year. They are lighter weight than the caterham ones, or more flimsy, depending on your viewpoint. The Flange that rests against the body is not perpendicular to the wing, so it doesn't rest flat against the body. It's also not deep enough so you cant drill some of the mounting holes- theres no fibreglass to drill them in. You have to drill your own mounting holes, but I was expecting that. I fitted one, but it was a right pain and I'm not happy with how few fasteners I could use. Am about to buy caterham ones to replace it. I still have the drivers rear wing unused, you are welcome to it if you want.

I had a speedo that stopped reading if I went over 60ish. was erratic when I indicated and dropped to 0 when I touched the brake pedal. Turned out to be rear lights earth. 2 black ring crimps bolted to the front 3way brake pipe union. unbolted ,cleaned, bolted back up tight, sorted. This obviously needs to be a very good earth, the lights themselves were not dim or behaving erraticaly ( like you see on dodgy trailers ) and the connectors were not corroded, my multimeter was giving a reading of under 0.1 ohm This may not be the cure for your woes, but its an easy thing to try. adam

Hi, I had a go at fitting stripes, I found it quite straightforward, you spay water/detergent onto the panel which allows the stripes to slip around till you are happy with location, then squeegee the water out. 3 years on they are still stuck well. just got some off ebay with the 'CATERHAM' lettering to go on the sides. cheers adam

Apparently I need a new gearbox and propshaft , I didn't think there was that much damage, but if CC are doing it then .... So this is turning into an expensive and time consuming repair, all for the sake of a couple of washers. adam

Well, I have to say hats off to CC for service. I told them about my oil seal woes, expecting at best to recieve a replacement seal ( self build car, out of warranty) The next day a van turns up to take the car away so that CC can replace the seal then deliver the car back again. So hurrah! Adam
