Dear All, Does anyone have a spare S type seat which they want to sell? It can be cloth or leather, condition does not matter, broken or cracked seat frames ok. Thanks, Chris Perry

Dear All, I have two part worn CR500 175/55R13 tyres going for free if anyone wants them? They have about 2mm to the wear indicators at the centre of the tyre so only good for trackdays. Collection only from Kidderminster. Thanks, Chris Perry

Dear All, Wings and side impact bar now spoken for as well.

Dear All, Seat and Diff are both spoken for. Wings and Side impact bar still available.

Dear All, Garage clearout time! Buyers to collect from Kidderminster evenings or weekends. Front and Rear GRP Wings Full set of Front and Rear GRP black metric chassis wings. Pair of front wings are cracked and scuffed. Pair of rear wings were brought at recent Caterham gumble sale but the holes drilled in the mounting flange did not line up with my car. Wings have been drilled for stone guards. Would suit trackday warrior, racers/sprinter types where condition is not important. All free to a good home. Low Back Caterham GRP race seat Not tillet but the narrower ones that pre-dated them. Scuffed and scratched but has brackets. Would suit trackday warrior, racer/spriter types where condition is not important. Free to good home. Caterham supplied Quaife Sierra Rear Differential, Not LSD Came fitted to my 2010 Academy car. Usual clonks, groans and knocks. Needs a rebuild. Think the ratio is 3.91. £50.00 Caterham Metric Side Impact Bar Used for one season. No damage but a few scuffs. Free to good home.

Andrew, You could take it to McMillan Motorsport near Hinkley. If your car is ex-graduate they will probably already know it! http://mcmm.co.uk There is also Bookatrack at Donnington Park who are a little further away. Both are good. I guess the set up is personal and depends on your car. But i have front, 1mm toe out, 2 1/4 deg camber and 2 + 2 caster. There is 15mm rake front to rear. Tell McMillan/Bookatrack what you use the car for and they may be able to offer some advice. Hope this helps. Regards, Chris Perry

Dear All, Thanks for the replies. Today on the Northampton Motorsport rolling road my car made 143 bhp with 120 lbsft of torque. The max figures were no different to the standard Caterham 140 ecu and map but certainly my car now drives a lot better from lower down in the rev range now and idles a lot better than the standard Caterham ecu and map. They did comment i may be able to get more power if i used 98 octane fuel and cooler spark plugs. The standard Caterham ecu cannot be re-mapped and is locked. I was only able to re-map my car as i have brought a new MBE ecu. Hope the helps. Regards, Chris Perry

Dear All, I am off to a rolling road tomorrow to have my 140 Sigma supersport re-mapped. Before i go, can anyone confirm what the caterham quoted max bhp and torque figures are please? I have found 140 bhp @ 7200 rpm and 120 lbs/ft @ 5790 on the net and blatchat. Can anyone confirm? Thanks, Chris Perry

Dear All, Does anyone have any surplus Caterham carbon wings or nose which they no longer want? Water damaged parts are ok, but they need to be Caterham original parts not aftermarket and preferably from a metric car. Regards, Chris Perry

James, Dampers and ride is all subjective. One persons magic carpet is anothers shopping trolley. Before you spend the money i would try and get a passenger ride in a car with the set up you are being offered. I have an old Low Flying article written by Gary May of Juno Sports Car/Freestyle motorsport which may be of interest to you and i can email with regard to spring rates. You could try putting some zip ties around the damper rods on your car and go for a drive. Find some pots holes and bumps and see how much of the current suspension travel you are using. This may give you an idea of the spring rates you may need if you buy some new dampers or if your car is just too stiffly sprung. If all this is too much effort, start saving for the CSR! Regards, Chris Perry

Dear All, I recently had some electrical issues with my 7 which i could not fix with regard to high oil pressure and a bouncing rev counter needle. After may hours of head scratching and discussion on blatchat i gave up and called the experts at Bookatrack Caterham. Bookatrack collected my car and fixed the problems which was a broken connector in the oil pressure sender loom plug and a plastic clip which was missing from the ecu connector. So i thought i would post about what excellent service i have had from them. Chris Perry

Adam, I have done this conversion. I brought a handbrake cable off a csr from caterham. This has the correct end fittings, however it is too long. I fitted it to the car to work out the correct length of inner wire and outer casing. Then sent it back to speedy cables who shortened it and fitted a new end fitting which matched the original. If you want to re-use the existing cable, you could try contacting speedy cables who may be able to cut the old end fittings off your existing cable and fit the ones you need. When mounted at the 12 o'clock position on our de dion tubes, the golf mk4 caliper's bleed nipple is below the top of the brake cylinder. Meaning you will never get the air out of them on the car. Took me and my brother 1.5 hours to work that one out! The only way i could bleed them was to fit new flexible brake lines, so you can hold the caliper with the bleed nipple at the top off the car. I brought the brake lines from Hel as you can specify the end fitting and thread sizes. From memory, the golf calipers have a different thread where the brake line screws into the caliper in comparison to the sierras so the solid caterham de dion brake lines dont fit anyway. If you are using caterham 13" 8 spoke anthracite wheels you will have clearance issues with the inside of the rim and brake caliper body without grinding the top of the caliper of making a new de dion ear or caliper carrier. 15" 8 spoke anthracite and MB mag alloys will be ok though with no grinding. Hope this all helps! Regards, Chris Perry

Hello Jonathan and ChrisC, This morning i checked the rev counter plug earth and engine loom earths and all were ok. I had my engine upgraded from 125 to 140 bhp about two years ago and still have the old 125 bhp MBE ECU. In desperation i swapped the 140 bhp ecu for the 125 bhp ecu and the rev counter gauge stopped bouncing. I think i have an ecu problem. A eureka moment! Thank you both for your help over the last few weeks. I can feel another upgrade coming on. Regards, Chris Perry

Hello Jonathan, Yes i think it matches the car. Regards, Chris Perry

Hello Jonathan, Yes that is the wiring diagram in my build manual. Is the ground (earth) G79? Excuse my ignorance when it comes to electrical stuff and being able to read circuit diagrams. I understand hacksaws and hitting things with hammers much better. And im not ruling them out soon! Regards, Chris Perry
