The skyline has lows 400's to the ground...Sammy choose the sr because its way lighter and shorter than an rb, so he mounted her further back in the engine bay for better weight distribution. Its attached to a z32 trans which also sits futher back than the original rb20 trans....Tiger racing cars are known for making mad power of of SR's. I will be at D1 next month when this car makes it official release into the world of drifting...the last successful skyline in d1 ended up meeting a wall last year...so hopefully sammy can turn things around.
