solid axle, if done properly, would never experience wheel hop issues that irs have
wrong, wheel hop isn't an issue on our cars in all the time I've seen em drag and been driving one.
IRS has less unsprung weight, meaning it's easier for the suspension to control. Wheel hop is caused by the loading of the suspenion and having it spring back. On a leaf spring car it's a huge issue as the axle will load up and twist the spring.
a good 4 link will get rid of a lot of it, but it's not perfect.
Celica and MKI supras had solid axles stock, the MKI axle was beefed up because of the larger motor. After looking at the photos I have of MKI's, they don't appear to have a leaf spring setup.
I'd have to see what the design is, but my point was that IRS generally DON'T have wheel hop issues as the real cause if the pinion climbing it's way up the ring gear, while on an IRS it doesn't have this force.
