DO NOT perform this. This damages the rear crossmember. The mod is irreversible. Not only that but I'd hate to keep having to readjust the alignment everytime I go over a set of railroad tracks. I'm sure that bolt will not hold that arm in place when I'm at the road coarse driving the hell out of it.
The rear control arms for the IS300 have adjustable camber. If you're looking into making your rear camber adjustable, use the camber bolts and control arms for the IS300. Yeah, the ISx50 uses 5-link rear and the IS300 use wishbone rear but the rear control arms are adjustable.
Also using any sort of spherical rod end will be a harsher ride and will wear out from the dirt and grime getting in. You may use a teflon reinforced inner race equipped rod end (which costs more) but it too will eventually wear out.

The front caster is not adjustable but there is a positive 0.5 deg and negative 0.5 deg lower bracket that can be purchased. I've replaced both my front caster brackets with 0.5 deg positive brackets.
I've been eyeing the IS300 SPC adjustable ball joints for a while. Its good to see someone has already used them with success. I'm debating about installing a set on the next set of tires I'll be purchasing.

This arm is not going anywhere after it is bolted down. There are teeth on the bushing of the LCA that dig into the cross-member and keep it in place.
I wouldn't do this if I did think it would work. Miami Chassis has been doing this to fix all the high end cars in Miami for 15-20 years now. Everytime I go to Miami Chassis I see Porsche's, Mercedes, BMWs, $80k plus cars getting their camber fix.
Plus I know at least 7 family members and buddies who have had this done and no issues what so ever.

If all you care about is reducing camber it will work. If you're going to actually drive the car, you'll be very disappointed. Supras have a cam adjustment system. Most alignment shops are staffed with idiots who think they know better than Toyota and don't tighten the adjustments to 166 ft-lbs as the FSM says. So the alignment goes to crap very quickly when the cams rotate and the original settings are lost. AMHIK.
This solution will work for someone who does not stress the car much. Don't expect it will hold at the track because it won't.

No, he's talking about the bushing at the rear of the lower control arm. Lexus has different parts available for this to change caster if the factory setting does not meet factory specs. It's in a Lexus Service Bulletin.

It MAY work if you replace the bolt with a flanged-type bolt with grooves that will "bite" into the lower suspension arm to prevent the shifting.....or, use the oem camber bolt of the IS300 or 2GS (thats IF its the right size and long enough).

Is it this one (OEM/Ball Joint/ U-joint press tool set)
http://www.autozone.com/autozone/acc...er=557231_0_0_
Were there any special adapters needed like this one (OEM/ 4WD Ball Joint Adapter Set)
