papak Posted July 10, 2015 Share Posted July 10, 2015 Although the Birkin XS is wider in the cockpit, the width for the seat base is still 18" at the floor. When raised up by sitting on a slider or fixed mount, there is probably 18.5-18.75" clearance. I am looking for decent, somewhat comfortable seats that might fit this chassis. I have looked at the Sparco Sprint and the OMP TRS, the two narrowest I can find. The Sparco dimensions show 19.3" at the front and 16.15" at the rear. The OMP shows 18.9". Anyone have experience with another option? The Birkin seats are a fiberglass shell with upholstered pads installed. OK but not my first choice. Kirkey has some that would fit but that's a little more "track commitment" than I am interested in. TIA Link to comment Share on other sites More sharing options...
toedrag Posted July 10, 2015 Share Posted July 10, 2015 What about the Momo Supercup (std size, not the XL)? http://www.momousa.com/images/products/Racing/seats/supercup/tabellasupercup.jpg Link to comment Share on other sites More sharing options...
TheDingo8MyBaby Posted July 10, 2015 Share Posted July 10, 2015 (edited) Tillets are suprisingly comfortable, even just as a fiberglass shell. There are several here that would fit your criteria: https://www.tillett.co.uk/car-racing-seat.asp I find Bride seats to be well made and are also small as they are made for the Japanese domestic bum. the 470mm should meet your needs here: http://i.imgur.com/DozLpww.jpg Edited July 10, 2015 by TheDingo8MyBaby Link to comment Share on other sites More sharing options...
toedrag Posted July 10, 2015 Share Posted July 10, 2015 Corbeau Sprint, LE-Pro, LE-Driver, LE-X. Zolder is another brand to look at. These will be a bit pricey, and some may only be available from the UK.

JohnCh Posted July 10, 2015 Share Posted July 10, 2015 The Cobra Racer Pro and Racer Pro V are only 450mm (~17.72 in) wide, so might be worth a look. I've had the Sparco Sprint in 2 cars and it's a nice seat for the money, although the fabric on the side bolsters wears easily. I use the optional kidney pads for additional lumber support which makes them tolerable. My Westifled has MOGs which are the most comfortable seat I've ever sat in. Full disclosure, I developed a very bad back 7 years ago, and most car seats generally become pretty painful after 20-30 minutes, with the MOGs though, my back actually feels better after a drive. Interestingly, and despite the outward similarities, the Tillets are not comfortable for me. In my experience, backs are like feet; everyone's are shaped a little differently, so what is comfortable for one person, may not be that great for someone else. If you have sensitivity in that area, it's worth trying before you buy. -John Link to comment Share on other sites More sharing options...
turboeric Posted July 10, 2015 Share Posted July 10, 2015 Pretty expensive, but these are good. http://parts-shop.westfield-sportscars.co.uk/seats?product_id=617 There's also a wide range of narrow seats available from these guys: http://www.europaspares.com/interior-parts/seats/custom-classic-kitcar-seats.html Link to comment Share on other sites More sharing options...
papak Posted July 14, 2015 Author Share Posted July 14, 2015 Anyone have any experience with the Corbeau A4? It seems to fit the car and the pricing is reasonable. Link to comment Share on other sites More sharing options...
MightyMike Posted July 15, 2015 Share Posted July 15, 2015 You may be able to pickup a set of used Elise or Exige seats from Sector 111 or on LotusTalk. Link to comment Share on other sites More sharing options...
rnr Posted July 15, 2015 Share Posted July 15, 2015 I have an OMP Pista in mt Ultralite. The top of the seat is slightly wider than the opening but I have it setup such that the left edge of the seat goes just under the chassis rail and gains an extra inch of width.

Kitcat Posted July 15, 2015 Share Posted July 15, 2015 FWIW-the Caterham S3 carbon fiber seats just barely fit in my Birkin. It was so tight, they would not slide on their sliders. Link to comment Share on other sites More sharing options...
ropaSeven Posted July 15, 2015 Share Posted July 15, 2015 My old 1999 Birkin has modified Porsche 914 seats with adjustable headrest. Re-padded with foam from from aircraft spruce?? And covered in cloth centers with vinyl sides. They are fairly flat in the seat area so extra padding under your thighs near the knee is needed (for a more bucket look/feel), so your legs won't get tired on the longer trips. We have done 300 mile day trips with no tiredness. DJ Link to comment Share on other sites More sharing options...
papak Posted July 21, 2015 Author Share Posted July 21, 2015 I just ordered an OMP TRS-E ES from Pegasus to try. Definitely narrow enough to fit in the chassis. I am still a bit concerned about the "butt capacity". About $400. Link to comment Share on other sites More sharing options...
