combine Posted June 26, 2010 Share Posted June 26, 2010 In place of original leather seat , presume you use the two rails that are fixed to the old seat , as its the only way to attach to floor apart from fixing to ali floor . Link to comment Share on other sites More sharing options...
Myles Posted June 26, 2010 Share Posted June 26, 2010 The standard fitment of the race seats does use adjustable-rails between seat and floor. Can't confirm if they are the same rails or not. Whatever you do, make sure you use a couple of 'penny' washers each side of the floor (underside at least) to spread the load to the floor. You might well find that you'll need to stack up some washers at the front of the seat to make the angle comfortable - don't over-do it and do make sure that there's enough thread left on the bolts for the under-floor nuts. If you do need longer bolts at the front, make sure that they are of the correct-spec steel (CC-parts can help - they supplied me with *much* longer bolts for this purpose in the past). 🙆🏻 🙆🏻 🙆🏻 🙆🏻 🙆🏻 Alcester Racing 7s Ecosse™ 🙆🏻 🙆🏻 🙆🏻 🙆🏻 🙆🏻 Alcester-Racing-Sevens.com Link to comment Share on other sites More sharing options...
combine Posted June 26, 2010 Author Share Posted June 26, 2010 That makes sense now , wasn't sure where the washers went ! So they take the place of the original bars attached to the leather seat. Still seems daft fitting to thin ali floor and not using bars to spread weight to previous bolt holes . Link to comment Share on other sites More sharing options...
Englishmaninwales Posted June 26, 2010 Share Posted June 26, 2010 Still seems daft fitting to thin ali floor and not using bars to spread weight to previous bolt holes . If you are not trying to lower the new seat and wish to avoid fitting to the floor, adapt the mounts of the original seats for the tillets seats. Blat mail me and I'll return some photos, as Ive just been through this task. Malcolm Link to comment Share on other sites More sharing options...

Leadership Team SLR No.77 Posted June 27, 2010 Leadership Team Share Posted June 27, 2010 So they take the place of the original bars attached to the leather seat NO! You must use a mount/runner under the seat. If you bolt the seat directly to the floor with any kind of variation in spacers front to rear, which is usually needed to get a suitable angle, the mounting bolts will put strain on the captive nuts inside the seat base (actually "BigHead" fasteners) and they will become detached. The adjustable runners used on the standard seats can be re-used on Tilletts, or you can get a fixed mount from Caterham that is a couple of modified sections of 25mm square ally tube. The runners bolt directly to the seat, then use spacers under the runners to achieve the desired reclining angle - sat flat, Tilletts are more upright than standard seats. Stu.
