Stock seats on 111S weighed approx 8.8 kg.offroadr35 said:...any idea what the stock seats weigh (non touring)?
Paul, the stuff behind the seat has the fuel tank in it, you do not want to be drilling holes in that.Paul MD said:errr.... there is a piggin' geat Aluminium cross member where the front seat anchor is and (if memory serves) similar at the back formed by part of the rear firewall x-member as it angles down?
Granted running between them is a piece of tin-foil (designed to vibrate nicely and necessitate wedging a wad of cloth under the seat). The undertray isn't visible inside the car and is a second skin running along the bottom... so visible bolts won't be an issue methinks?
Fitting it low enough to be exact.jdl8r said:I believe the Sparco Roadster seat will fit [drivers side]... Mounting is the only real question?
Yup.. And it's only 1 1/2 to 2mm thick and I do *not* trust it to carry the required 750Kg (1400lbs?) loading that crotch straps can give.Bill Swizz said:The floor is only one layer not two as shown by the people with the footwell corrosion having holes right through the single layer and being able to see the road.
Yup.. When attaching to the rails it's a good idea to include a steel brace between the runners, so they can't be pulled inwards during a crash.The straps can either go back under the seat and attach to the waist seatbelt mounts or can go sideways and attach to the seat rails.
Yup.. Some people also drill through the rear chassis channel and use an eye bolt + spreader plate under the car to fixate the lap belts.I believe some people have used spreader plates under the floorpan to do this but then as Arno says you have bolts sticking out under the car.
2 things with that.jdl8r[/i] [B] I can't believe that a kit for aftermarket seat fitting doesn't exist already? We can't be the first folks in the world contemplating a seat swap for the likes of Sparco/Ricaro etc. [/b][/quote] Not the first said:I fail to see why a crotch strap couldn't be affixed to the front seat anchor x-member (the one you stand on to get in) but will defer to Lotus on that one.
I thought you use could use Corbeau seats on both passenger and driver's seat. I am about order. Am I incorrect?Unless the seats are specifically made for the Elise then hardly any fit.
Or you can fit only one seat and keep the standard passenger seat, or remove the passenger seat completely.
The only one that has a chance of fitting is the Cobra Monza, but even with his one you can't really fit 2 at the same time unless you don't mind that the driver's seat can't be moved back very far anymore and it's interfering with the passenger seat. This is installed by KMS in Japan I think..
Lotus sells a Corbeau motorsport seat, but you can only fit one on the driver's side. They just re-cover the passenger seat in the same material/colors, because 2 of these would not fit in the car.
Biggest problem is often the width of the shoulder area and the width of the seat base, which causes problems with either the passenger seat or fitting it between the chassis side-beam and the center console.
A big problem is also to fit the seats low enough. Unlike most other cars the seats on the elise actually drop below the runners at their lowest point, so most side-mounts are way too high and you need custom brackets made. Otherwise you feel you are sitting too 'high up' (a common complaint with the Lotus/Corbeau seat)
This gets especially tricky if you want to keep the driver's seat slider as the seat bottom needs to be profiled to clear the adjustment mechanism and no off-the-shelf aftermarket seats have this AFAIK.
For this reason there are several aftermarket seats available for the Elise (for instance Reverie carbon seat | | Reverie or www.Eliseparts.com seats) , but not from the 'big' names like Sparco, Corbeau, etc.
Most of the aftermerket seats are meant to be bolted in place and use fixed seat mounts though.
Structural 'oddities' of the Elise also mean that you have to plan/design where/how to attach/anchor seat belts/harnesses.
For instance you can forget using the floor panel under the seats. It's totally non-structural and way too weak to attach any belts, even with load-spreader plates (not to mention that you'd have bolts sticking out under the car, ready to 'catch' on things).
You need to use the chassis beam(s) and seat mounts/rails for this purpose.
It's not rocket-science, just needs a little more planning and thought than in 'normal' cars.
