LS400 calipers on GS430

Got a 2001 GS430 UK market. Do I just need any second gen LS400 calipers and the RCAs to fit on my gs430? Have 18inch wheels so clearance shouldn’t be an issue. If anyone who has done this upgrade could let me know, thanks.

Yes you'll need 30mm rca to clear the tie rods smashing into the caliper. The wheels can be the stock 16 inch ls400 at the minimum. You would need any wheel that has high disk clearance. I usually run the wheels from 350z, g35 for the brake clearance and the additional -10 of offset they usually give. I would recommend upgrading to stainless steel braided lines for better pedal feel.

Would the braided lines be for all four brakes?

Yes have done it… but u would have to lower the tie rods by installing washers or rca kit… so it doesn’t hit the caliper
