Jic use to make arms but they don't any more. There is one company called a1 that make toe camber traction arms but they made to order. I was told buy the company it takes three weeks to make per order. Other than that there is an alignment kit which is just a bag of bolts on ebay and that's it. From what I've read on supramania.com the mk3s factory. suspension is fully adjustable
JZA70 MK3 SUPRA pre-production parts test fitting was successful on Anthony's car.
These will be available for pre-sale for $1000 with delivery in March.
I also did a measuring session on the rear arms - Traction, Toe, and Camber so those production parts will also be available in the future following the coilovers.
