Basically the title... and most importantly why?

My car is daily driven, no track days or drag strips.. sometimes spirited driving on roads.. but thats about it.
Car is lowered on whiteline springs and have spacers.

I am looking rear suspension adjustability and lessen tyre wear.

Thanks in-advance!

I think community consensus is that SPL is robust and sufficient for street Supras, but anyone trying their hand at racing should probably cop for Verkline. Verkline parts seem to be better at handling track abuse, according to the HPDE guys.

I don't think I've seen an SPL failure on a street car, but I'm not familiar with the chatter that might happen on FB groups.

I have a full SPL setup and have enjoyed it tremendously. Glad I did it, and asked myself the same questions before I decided. My car has been doing well and I've had no issues after thousands of miles. Doesn't mean something can't happen in the future, but so far so good and I really like them.

I think Bryan has quite a few documented failures of SPL parts used in an HPDE/Time Trial setting. I'm an HPDE/Time Trial guy, so I have Verkline stuff sitting in a box for install this summer.

I will go back to the OP and follow up with a "what are you looking to achieve" question with the use case (no track/drag strip) mentioned. What are the tire wear issues?

What I'm getting at...adding a sh!t ton of adjustable but kinda harsh spherical bearings that need a whole lot more care and feeding than the stock stuff might not be the only way to solve your issues.

Correct me if I am wrong. I looked at all the bearings for the SLG kit. They use the RSMX series from FK. Some bearings are even larger than SPL. SPL uses FK "mid tier" JMX bearings. SPL endlinks use the cheapest weakeast FK bearing available. RSMX > JMX. Does anyone know what are some bearings on Verkline parts?
verkline uses rodoball’s motorsport line of bearings

I wouldn’t touch that rear arm kit.

besides the fact that I’ve got 0 confidence in anything they design, they’re running the same fk bearings that fail on SPL stuff.
Incorrect.

This is correct. Ive had the SPL and now SLG kit. The SLG bushing are way beefier. They also dont add unnecessary adjustment to arms that dont need it like SPL does.

the alignment shop says i dont have any adjustability left.. either I increase the height or upgrade the suspension for more adjustability.

i dont want to increase car height..

Not a Corvette.

As noted above, find a better alignment tech/shop.

Do you have the alignment specs the car was running with these tires?
