Tony Martyr Posted January 12, 2002 Share Posted January 12, 2002 I am replacing the standard 1996 front suspension with a widetrack, adjustable spring seats, 0.5 inch ARB and 250 lb springs. Are these springs a standard Caterham part that I have to buy with the rest of the kit or are they purchased from 3rd party suppliers, for a better price. If the latter what is the spec in terms of free length etc? Link to comment Share on other sites More sharing options...
Rob Walker Posted January 12, 2002 Share Posted January 12, 2002 Caterham do not stock a wide range of springs. They probably have 250 lbs fronts and 215 rears. If you want 200 lbs try Deemon Theives or Miserable Motor Sport. Gary May at Juno also can supply. you will have no problem sourcing the fronts in the correct lenght 7" but the rears are more difficult as 13" length is ideal for the rear end AFAIK juno have these. If you go for 14" you end up with too much pre load to get to the correct ride height and 12" are too short. Rob. Link to comment Share on other sites More sharing options...
dalec Posted January 12, 2002 Share Posted January 12, 2002 I have a 1997 de Dion. Watch you don't go too hard at rear. I put 250 front and 180 rear - it wasn't brilliant! I now have 250 and 110lbs (yes 110), however I now have front and rear adjustable anti roll bars. The difference is unbelievable. The car is comfortable, has little roll, goes where you point it, sits down on acceleration and grips like hell. I had my suspension designed by Alan Staniforth and the cost was worth it. Cr used on road, track, sprints and hillclimbs. Link to comment Share on other sites More sharing options...
Allen Payne Posted January 12, 2002 Share Posted January 12, 2002 Tony, I've a set of 250lb front springs, from Caterhams, that would not fit my car (1992 non-widetrack), if you want them. (Including the larger top collars for them) They're a very tastefull bright green!

Tony Martyr Posted January 13, 2002 Author Share Posted January 13, 2002 Allen, thanks I will email you off forum What spring rating does the Superlight R model come with as standard? Anyone know, as this should be a good datum for other K series cars Link to comment Share on other sites More sharing options...
captain chaos Posted January 13, 2002 Share Posted January 13, 2002 I'm sure the fronts are 250 but I don't know about the rears. Link to comment Share on other sites More sharing options...
jonhill Posted January 13, 2002 Share Posted January 13, 2002 SLRs have the same set up as SLs as std - 150 lbs with 18mm arb at the front, and 90/150s at the back. 250 + 13mm arb at the front is softer (in roll) than 150 + 18mm, and when I tried it (with the std rear setup) gave a much better grip balance, with the understeer I was experiencing banished. It is great on bumpy roads, but IMHO too soft for the track. I got some short springs from Caterham for the rear, and there was no problem fitting them, I just had to move the threaded collar onto a different groove on the damper body. I can't remember what length they were, 11" or 12" I think. Jon Edited by - jonhill on 13 Jan 2002 13:02:03 Link to comment Share on other sites More sharing options...
elie boone Posted January 13, 2002 Share Posted January 13, 2002 Tony, If you need new springs try D.Faulkner springs they can make whatever spring that you like and have an excellent service.They also have the most common springs on stock Tel:01234 543049 Link to comment Share on other sites More sharing options...
