Graham Sewell Posted December 19, 2002 Share Posted December 19, 2002 Has to be the 1995 live-axle because that is the one that I have got Low tech luddite - xflow and proud! Link to comment Share on other sites More sharing options...
AMMO Posted December 19, 2002 Share Posted December 19, 2002 I also have a 1989 big tube chassis. Must be a bit heavier I would have thought. Probably a bit stronger too. Is yours a De Dion? There are some strange bits on my De Dion. It has live axle rear shocks. The shockers mount through the De Dion tube, not on a bracket welded below. The A-frame and geometry is different to the later cars. I'm not making any major changes to it as it handles really well. The best person to ask about chassis information is Bruce at Arch Motors.

RiF Posted December 19, 2002 Share Posted December 19, 2002 Standard K chassis is the same as the R500. Only changes are for a race chassis. This is on all current models. Don't know when this changed. Info from Caterham and Arch. Richard in France Awaiting chassis to start building my Duratec 7 😬 Link to comment Share on other sites More sharing options...
Paul D Jones Posted December 19, 2002 Share Posted December 19, 2002 Acrh told me there 32 different ones [new ones ] They are all the same by design just extras [ little brackets etc] Except the R500 as this is built using CDS tube but the same by design. Caterham told me also the R500 has extra powder coating [when pressed he said it was just the engine bay all black] Does this help? Paul.

eric Posted December 20, 2002 Author Share Posted December 20, 2002 I have a de dion. This chassis has a very good performance, but I don't know the others Normally, the more recent ones are the best It is different, I think for the A frame, the spax and the way they are fixed at the rear, You can see them behind the roll bar and there is one tube under the gearbox between the right and the left side of the chassis. For me it is perfect, Link to comment Share on other sites More sharing options...
Bafty Crastard Posted December 20, 2002 Share Posted December 20, 2002 My under standing was that the R500 is the same as the R400 and R300. The other seven models are different, watt linkage, underslung rear anti roll bar and the rest.

Bob Corb Posted December 20, 2002 Share Posted December 20, 2002 There are subtle differences between a true "R500" chassis and a superlight type. A true r500 chassis has no triangular brackets/bosses in the corners of the cockpit behind the drivers right shoulder, nor does it have a wiper motor bracket and presumably washer bottle amongst other things. A lot of R500s are built on the normal SLR 98MY (or maybe the 01) chassis which allows installation of screen/wipers etc. I'm not sure what the difference between the SLR98(?) chassis and the SL96.5. I have an SL96.5 chassis (2001 superlight car). It has the rear watts link points and lower rear ARB mounting which differentiates it from the 96on Roadsport chassis. It now appears roadsports are using this chassis too Pre 96 dedion chassis dont have the front anti dive geometry or tunnel mounted handbrake of the post 96 cars. The anti dive is a moot point in many peoples opinion (I cant comment). Race chassis are different to all of the above. They have welded engine bay triangulation, short passenger footwells, thick honeycomb floors....

elie boone Posted December 20, 2002 Share Posted December 20, 2002 I have a live axle, when i ordered it i did ask for a Scholarship chassis and someone at Caterham marked "sportchassis" ( in ballpoint ) on the order so i wonder if there are different chassis spec. for live axle chassis aswel.

eric Posted December 20, 2002 Author Share Posted December 20, 2002 the race chassis often have no numbers quickly visible (pedal box), some people said that sometimes there is no numbers, always no carrier for spare wheels .... or no wiper motors mounts Link to comment Share on other sites More sharing options...
Silver 21 Posted December 21, 2002 Share Posted December 21, 2002 All From what I can remember: 1.Post 96 Live axle chassis's are different in having extra mounts front suspension 2.Race Chassis's have their handbrake under LH side dash and short passenger footwell even on K series cars and extra bracing under the seat areas (option I think) Graham The not so New Competition Secretary, in fact already jaded 1700 Live Axle X/Flow, new pb at Curb, Loton Park and Shelsley Walsh in 2002 Link to comment Share on other sites More sharing options...
