By using computer engineering and digital design STOMSKI RACING has developed the FIRST truly symmetrical 911 Semi-Solid Engine/Transmission Mount, thus allowing you to run stiffer mounts without sacrificing comfort or ride quality.  Our symmetrical design allows you to custom tune your ride- determining feel, function, and fun.  We provide 3 different durometers of inserts that allow you to custom tune your ride, now, and later if your application might change.  Because our SS mounts are SYMMETRICAL, you can now properly use them either as an engine mount OR inverted as a transmission mount. Unlike other non-symmetrical SS mounts, there is no compromise when using SR016 inverted as a transmission mount because SR016 is symmetrical and thus FULLY supports and FULLY absorbs in BOTH positions/directions. Road tested and track proven, STOMSKI RACING's SR016 provides better shifting, better weight transfer, better handling, crisper throttle response, better acceleration, and of course GREAT looks, without any loss of comfort.  Mounting  comes complete with an  aluminium housing, stainless steel sleeve and disks spacers & a M12 Schnorr washer. Sold as 1 Pair (2x Mountings)
