Trailer Size / Requirements - S3

[chrisbeddoe]

Morning All,

I am looking to get a trailer for my R500D and have found a Brian James Clubman I am interested in but want to confirm the bed is large enough. The bed is only 10ft9 by 5ft 6 (3.27m x 1.67m) which leaves little to spare! 

Has anybody run a trailer this size, it this large enough (and the weight far enough forward) or should i wait out for a larger one to come onto the market?

Many thanks, Chris

My trailer for the S3 R400D has a bed that is 3.35m x 1.82m and has plenty of room each side with space at the front and rear to allow for a sloping wind deflector and clearance to the vertical loading ramps at the rear when folded, so could be shorter without these two features. Having wheel stops allows for precise positioning and weight distribution, with the axle being 0.20m behind the middle of the bed to put 70kg of the 800kg total loaded trailer mass on the tow ball:

I have a PRG mini sport with an almost identical bed size, and my S3 is fine on it. Just need to be careful driving on it so that the exhaust isn't caught on the side.

Assume you have higher unbraked trailer weights in Canada looking at the photos, unless you don't use shunt brakes over there..?

In Alberta the un-braked trailer weight limit is 907kg (2000lbs), in BC and most other provinces and territories and states in the US, it is 3000lbs, although in general un-braked weight limits only apply to single axle trailers. Hydraulic surge brakes are fairly rare, typically most braked trailers use electric brakes with a dash-mounted controller for setting the resistance and triggering levels.

In the case of my trailer for the Caterham I designed it to stay within the 907kg limit with Caterham, tools and extra fuel on it, the trailer on it's own weighs 240kg or so, the Caterham 540kg or so and the rest about 40kg for a total of about 820kg. If I had bought a commercial aluminium trailer, it would have weighed about 350kg and taken me over the allowable limit.

Instead I wanted a trailer that was both light and can be stored on edge in my garage in very limited space, so I designed and built it so the wheel and suspension units slide out and the wind deflectors and spare wheel have "R" pins holding them on for easy removal in a few seconds.
