The best seat for tall and larger drivers.
Everyone's body shape and size is slightly different, but typically if you are 6' 2" (188cm) or taller, then the Evo XL provides extra support in the back, neck and head areas. 
It is also a great seat for people who are broad at the shoulder. Also very forgiving for wider drivers typically up to around 25 stone (158kg).
 
EVO II QRT has the quality and value you have come to expect in the Evo seat line including a unique shell shape that increase rigidity without adding weight. The EVO II QRT is now made with Sparco QRT Technology which results in an ultra-light shell. The EVO II QRT is 7lbs lighter than the previous version. The Evo II QRT introduces re-engineered seat proportions, which provide greater ergonomics. The result is a seat that is both taller and slightly wider than the EVO for taller drivers. The seat belt slots are also repositioned to sit more level with the driver’s shoulders. The EVO II QRT is FIA approved.
QRT Technology gives an unparalleled mechanical strength/weight ratio for fiberglass composite racing seats. QRT Technology gives an average weight savings of 30% when compared to standard fiberglass technology. The main benefit is that QRT seats approach the weight of carbon fiber seat at the price of a fiberglass composite seat.
Comes with integrated lumbar support
