Dave Rothwell Posted January 12, 2012 Share Posted January 12, 2012 Hope this isnt too numpty My Superlight is 1999 frame - will this be a metric or imperial chassis ?? Also can you get a SLR cage for this chassis and would the bushings for the side intrusion bars be already on the frame under the skins or would they have to welded on. Many thanks for any info gratefully received daveR Link to comment Share on other sites More sharing options...
Ivaan Posted January 12, 2012 Share Posted January 12, 2012 Dave, It'll be a good ol Arch Imperial chassis. Clive Link to comment Share on other sites More sharing options...
Sheds Moderator Posted January 12, 2012 Share Posted January 12, 2012 It will indeed be imperial. I think the bushings are on all 1999 era chassis, just covered by a skin if not needed. SLR type cages will fit this chassis, these are the ones with the 2 curved top tubes, and you can't fit a hood once on. Link to comment Share on other sites More sharing options...
Dave Rothwell Posted January 12, 2012 Author Share Posted January 12, 2012 Many thanks guys - I have had the car ten years and it's had an aero on all that time dont have a hood or anything so thats no problem, cheers again, daveR Link to comment Share on other sites More sharing options...
Adrian Williams Posted January 12, 2012 Share Posted January 12, 2012 Not all chassis of that age have the bushes. I know a number of people who've fitted SLR cages to cars of that age and most don't have them. Including my 2001 chassis which had to have them added.

Sheds Moderator Posted January 12, 2012 Share Posted January 12, 2012 That's unfortunate. Phone call to ARch with a chassis no then I imagine, or perhaps time to cut an exploratory hole in the inside of a sideskin. Link to comment Share on other sites More sharing options...
simonpa Posted January 12, 2012 Share Posted January 12, 2012 ...or just drill the heads off some of the inner sideskin rivets - than you can see from the inside without needing to drill any holes in the skin :) HTH - Simon Edited by - simonpa on 12 Jan 2012 14:52:18 Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted January 12, 2012 Area Representative Share Posted January 12, 2012 For the current "Caged" SLR cages there are four bushes required on both sides of the car. Two along the sill (the front of which are commonly used for petty struts and Roadsport cages) , and a further two in the chassis rail under the side of the scuttle. Our 2002 car had the bushes along the sill, but not the ones through the chassis rail. Edited by - Richard Price on 12 Jan 2012 15:07:03 Link to comment Share on other sites More sharing options...
Dave Rothwell Posted January 12, 2012 Author Share Posted January 12, 2012 Adrian - What was involved adding them - Side skins off and a welding job ?? Cheers, Link to comment Share on other sites More sharing options...
k.russell Posted January 12, 2012 Share Posted January 12, 2012 Dave, there was a thread discussing this a few weeks ago, have a look here there are a few links to pics and the pros and cons of the different ways to fit an SLR cage. hope this helps.

Adrian Williams Posted January 12, 2012 Share Posted January 12, 2012 Dave Internal skins part removed, rivets along the bottom edge remained in place all of which I did. Bushes are then welded or braised (not sure which) into place, no damage to paintwork on the outer skin which I certainly didn't do.

simonpa Posted January 13, 2012 Share Posted January 13, 2012 Dave - I've emailed this to you, but it may be useful to others thinking of going the SLR-cage way: It's a pretty simple job to check the bosses in place - you need to: o take a set out (access is probably simplest on the passenger side) o drill the heads off the rivets from the top edge of the inner sideskin, probably from about the middle of the door-sill to the underside/back of the scuttle (use a 8-10mm HSS drill on a slowish speed and stop when the rivet head turns) I then normally use a punch or big nail to knock the rivet through o pull the inner skin back and look with a torch to see which bolsses are in place Note - there are several different types of SLR cages (at least the ones I have seen), in how the front mounts are placed. I have seen: o front mounts bolt into bosses brazed underneath the top chassis rail (under the scuttle mounting bolts) o front mounts bolt *through* the top rail - usually with a bracket that feeds through holes in the rail to stop it collapsing o front mounts that bolt through the scuttle *above* the top rail, into a bracket that bolts onto the top rail - usually using the scuttle mounting bolts Are you buying a new cage or looking for a used one? It may be best to sort/buy the cage first and take it from there.. HTH - Simon Link to comment Share on other sites More sharing options...

Bradders Posted February 19, 2012 Share Posted February 19, 2012 Quick highjack. I'm new to Caterham having bought a Academy car two weeks ago. Being an Academy it has a full cage. I'm thinking this is a bit intrusive for road which is where the majority of it's time will be. Maybe the odd track day if her in doors approves. It's a Feb 2006 Roadsport but I'm unsure whether it's a metric or imperial? I understand that this was the year it changed. I'd like to put an FIA roll bar on. Is it a big job change across?

richy Posted February 19, 2012 Share Posted February 19, 2012 *arrowup*If it were me, I'd keep the cage and fit padding. Buy an aeroscreen with the money saved! Link to comment Share on other sites More sharing options...
Dignity Posted February 19, 2012 Share Posted February 19, 2012 Quoting richy: *arrowup*If it were me, I'd keep the cage and fit padding. Buy an aeroscreen with the money saved! Me too! Less risk of decapitation 😬 Link to comment Share on other sites More sharing options...
Roger Ford Posted February 19, 2012 Share Posted February 19, 2012 Feb 2006 Academy car will be the last imperial year. Link to comment Share on other sites More sharing options...
david nelson Posted February 19, 2012 Share Posted February 19, 2012 My 2001 superlight did not have the bushes at the front and none at the rear. Same solution as Adrian's to resolve problem. David Link to comment Share on other sites More sharing options...
