The EBR17+ bracket is designed to fit the seats into the newer Elise Exige adjustment runners from 2017 VIN serial number 1457 onwards. These 3mm thick steel brackets allow for the original OEM Lotus seat slider, allowing legroom to easily be adjusted to various drivers' needs. Angle and height are also adjustable via 4 bolts. Lap belt mountings are included to allow installation of a race harness. The EB6 brackets can be installed on the passenger or driver side and fit the regular-width B6 Screamer (with and without edges), the edge-less B6 Screamer XL (TIL-B6S-XL-C-43 & TIL-B6S-XL-B-43), B7 and B8 seats. The B6 Screamer XL with edges on (TIL-B6S-XL-C and TIL-B6S-XL-B) is too wide to be used with these brackets.
