Thank you for this thread, in fact, I was almost choosing SPL based on this forum review. However, the local shop we have here, they are professional for the track days events, and they will help/guide you on your car preparation. They do recommend Eibach.
He told me that SPL is more expensive, and then he mentioned another brand which the first time I heard about, its called Hardrace, he said many drifters (drifting drivers) use this Hardrace and they have two options, hard rubber or spherical bearings you can choose and it is cheaper (little bit) than SPL.
BTW Hardrace is very famous and high quality in AU (Australia).

I hope someone can give us an advise here, before I do my final decision, because the budget is limited
