thank you! it rides real well on the PBM coilovers as well, I can tell that an LSD and upgraded rear swaybars would help a lot in cornering. When I corner real hard now I will sometimes get a tire to lift and lose traction with a single tire.
I also notice that I NEED upgraded front brakes, so I have been considering what I can afford.. and what option I find best suited for me. I am considering the corvette z06 front 6 pot calipers with 14" IS-F rotors but not positive that it would clear my front wheels.. My other option is going with the stock TT supra 4 pots, but I haven't found anything reasonably priced yet, which has made me consider an LS400 setup but requires 17mm spacers.
The RJP GS 300 is looking great Joe! Keep us all posted on your brake dilemma, Both my GS and my SC could use an LS BBK, but like you, have some clearance issues vs. too much 'poke' with spacers. Hope you find a good solution!
I liked the ls400 brakes on mine but I got stoptech 14" all around for my other GS. They work much better. Also if you get a bigger front bar it'll help more than a rear bar for your traction issues. I got the supra auto LSD diff for mine and works great.
I am going to pull off a front wheel and see if it can clear a 14" bbk.. Although the downside to the 6 pot z06 calipers from what I've found is that they cannot be rebuilt, but instead have to be replaced. The LS400 calipers with a spacer will drop my front end even lower, which isn't really a problem with coil overs but would require a re-alignment.
So I think i'm going to be on the lookout fro TT supra 4 pot front calipers and see if I can get a set for under 500.
I picked up a mk3 supra ebrake from an 87-92 toyota supra, but have yet to find a company which can chop my stock cable in half and put a new threaded bolt end on it, which then can be used after mounting the ebrake handle to the center transmission tunnel. It comes out on the passenger side of the transmission tunnel so it would mount very easily to the passenger side. I plan on doing it this summer and will update you guys!
