Sits flush, where is no play with the bore. just between the studs where is play.

Cant figure out why, according to brembo these are meant for a LS400

How much play are you talking about. There is always some play.

A little bit of play nothing too crazy but there is some play.

Also there is no way a 5mm or 10mm spacer wont fit stock rims.

I can't see anything less then extended studs and a 15mm spacer atleast fitting stock rims.

Thanks to everyone whos went through all the trial and error to see what was needed to make this work! I really like the idea of having fixed calipers on all four corners for a total of 12 pistons!

It looks like 18mm is the minimum RCA height. I really like the 2007 3GS 18" 5 Spoke Chrome wheels. If I do this I'd probably paint the calipers gloss black.

Does anyone know about rear calipers and rotors? For instance, are LS400 rear calipers and rotors a direct swap onto the 2GS? Is it possible to put the stock 2GS front calipers onto the rear? I'm just looking to replace the stock rear calipers when I do the fronts, since they're ugly and made of iron as opposed to the LS aluminum calipers.

I purchased extended wheel studs and spacers from a local shop. I believe I needed .25" or .5" spacers. I was on a budget and the studs and spacers were an expense unaccounted for. I only had enough to do the front wheels. As a result, my front wheels stick out a little further than the rears. It doesn't affect handling or wear too bad. I'm not too savvy when it comes to DIY so I had everything installed at the dealership that I work at. Here's a few pics, hope this helps. Best wishes!
hi, just wondering if you have used factory 16 inch rims, as im doing the same upgrade,

thanks

Here's a closer look. Be sure to get hub centric spacers to avoid vibration during highway speeds.

Ill be installing the LS calipers with my gs460 wheels later this week. I think my 15mm H&R spacers will be enough for clearance.

Just picked up some IS250 17" wheels, hoping they will clear the LS or Supra calipers....

Finished the LS conversion a couple weeks ago. IS 18s fit perfect with no spacer.
