i see em on ebay a while back an thought nothing of it dont suppouse any one can shed some light were i can find sum as my cars so low but im sure i read that by using those engine raisers i could gain abou 40mm sump clearance
not sure where you get them from but 40mm spacers are abit extreme, you will lose the lower engine mount, and will take the driveshaft closer to the arb, can cause exhaust to rub, cons outweigh the pro imo
