Drumster Posted September 29, 2012 Share Posted September 29, 2012 I have an opportunity to purchase a 2008 metric roll cage (Roadsport with curved bars on the top) and this would be to fit on a 1992 de dion chassis. I've only had a quick look through the archives and it seems that it will fit with some spacers for the rear legs. Has anybody actually done what I'm trying to do? Just looking for confirmation before I spend my dosh. TIA Link to comment Share on other sites More sharing options...
Area Representative bluenose Posted September 29, 2012 Area Representative Share Posted September 29, 2012 There is one on Pistonheads and the advert says that it will fit an imperial chassis as stated by Caterham so I would think one would fit yours. It may be the same cage that Prangerman has on his car which I would have thought is an imperial chassis. Nick Link to comment Share on other sites More sharing options...
Cookie Monster Posted September 30, 2012 Share Posted September 30, 2012 Yep, Ive done it & it fits. You may need some spacers which I got made by Caged but it took them ages to do them(got the impression they couldn't be bothered but kept nagging a guy called Phil) & they cost £30 for a pair which is daylight robbery for two bits of metal. I think I have a spare set, which if you get stuck I'll sell. Phil. Link to comment Share on other sites More sharing options...

The Pikey Posted September 30, 2012 Share Posted September 30, 2012 Depending on what dampers you have you might have to machine down the heads on some M10 bolts to mount the cage as the buckets on the imperial chassis are deeper putting them closer to the damper. Imperial cage bolts have bolt heads which are about 3mm thick for this reason. J Link to comment Share on other sites More sharing options...

JEM Posted September 30, 2012 Share Posted September 30, 2012 Chris, mine is obviously a metric cage, but it came off an imperial chassis. As I understand a metric cage will fit and imperial chassis but an imperial cage will not fit the metric chassis. Jem Link to comment Share on other sites More sharing options...

Leadership Team SLR No.77 Posted October 2, 2012 Leadership Team Share Posted October 2, 2012 Quoting JEM: As I understand a metric cage will fit and imperial chassis but an imperial cage will not fit the metric chassis Yes, the big difference is the bosses on the middle legs that insert into the chassis (above the shocks) are longer/deeper on the Imperial chassis cage - the depth of the hole was reduced on the metric chassis. I suspect on the metric chassis this has given a little more space above the shock to use a normal bolt rather than the reduced head bolt needed on the imperial chassis. Middle leg bosses on an imperial cage will not go far enough into a metric chassis, but the reverse of this is that there is space left below the legs if using a metric cage on an imperial chassis... hence the need for spacers, although a suitable stack of washers will do the same job. I still have a hooped top metric cage available if anyone wants one? (advert here). Stu. Link to comment Share on other sites More sharing options...

DirtBuddha Posted July 13, 2022 Share Posted July 13, 2022 I want to order one of Caterham's new 'Track Day' cages (Double-D but without side bars) but am being told by Caterham that the metric cage will not fit my 2005 Imperial chassis car. Sounds like it will fit according to the above info, but requires spacers. Does anyone have any pictures? Anyone had any success fabricating spacers, or did you end up waiting on Caged to supply them? Link to comment Share on other sites More sharing options...
TomB Posted July 13, 2022 Share Posted July 13, 2022 Says online that these cages are special order - I hoped that meant you could order them to be manufactured for imperial and metric chassis. Are they made by Caged? Could they do a special order? Link to comment Share on other sites More sharing options...
DirtBuddha Posted July 13, 2022 Share Posted July 13, 2022 Indeed... I spoke to Caterham today and special ordered one for my car. Many thanks. Link to comment Share on other sites More sharing options...
TomB Posted July 14, 2022 Share Posted July 14, 2022 You ordered one to be made for your imperial car? Link to comment Share on other sites More sharing options...
