The first IS500 in the world to go full bolt-on and tuned.
A 2024 Lexus IS500 built to be the first fully bolt-on, tuned example anywhere — headers, valved exhaust and a full suspension package, done right the first time.
What went into it.
How it came together.
The IS500 is one of the last naturally aspirated V8 sedans anyone builds, and when this one came in there was no roadmap for it — nobody had taken the platform fully bolt-on and tuned yet. This car was the first.
PPE equal-length headers went on with a full Meisterschaft valved exhaust, giving the 2UR-GSE the breathing it was clearly waiting for. Springs, spacers, camber arms and LCA bushings sorted the stance and the geometry together, rather than one at the expense of the other.
Being first on a platform means solving problems nobody has written up yet. The factory dipstick fouled the new headers, so it was modified to clear them — at no charge, because that is part of doing the job, not an add-on.
Then the calibration. With no existing map to lean on, the tune was developed from scratch for this exact combination.
I had the guys at Carma Performance work on my '24 IS500 to make it the first one to be FBO & Tuned in the world. Can't say enough good things about the shop. Friendly guys, highest quality work, and most importantly they are zero BS, 100% transparent, and easy to deal with. They installed PPE equal length headers, full Meisterschaft valved exhaust, springs, spacers, camber arms, LCA bushings. They back their work fully, and were kind enough to adjust a dipstick to fit around the PPE headers for me free of charge.
