Lexus CT200h – Coilover Install

Coilover Install


Standard set of BCRacing BR Type Coilovers with the standard spring rates. Installation on this application was extremely easy.

The front being McPherson only requires a 14mm ratchet wrench to get under the cowl (so you don’t have to remove it), a 17mm socket and ratchet wrench to remove the sway bar endlink, and a 22mm socket & breaker bar to get the large bottom mount nuts loose. Tips: Jack up both sides of the car and place the car on jack stands as this makes the sway bar endlinks easier to remove. Loosen the nuts on the bottom mount and not the head of the bolt :-).

Out back use a 14mm socket or ratchet wrench to disconnect the sway bar from the control arm then a 17mm socket to remove the lower shock mount, and outer knuckle mount; these were able to be knocked loose by the head of the bolts (as they were easier to get to than the nuts). The control arm can then swing completely downwards allowing the spring to be removed with great ease. To fully remove the shock there are two triangular plastic pieces on the sides of the carpet that pop off to reveal nuts inside the trunk/hatch area. You will have to use a 17mm ratchet wrench and an allen wrench (sorry I forgot what size; it’s metric though) to remove the nut from the shock shaft. The shock will then be completely free and able to be remove from the wheel well. Tips: Jack up both sides of the car and place the car on jack stands as this makes the sway bar endlinks easier to remove. With the car on the jack stands use a floor jack to jack up the control arm your working on below the shock mounting point around an 1″ or so (varies). You will find at a certain point when jacking up the control arm both the lower shock bolt and knuckle bolt will have no load on them and you can pull them out by hand.

Installation of the coilovers was simply the reverse of the uninstallation of the stock suspension. The front coilovers are a direct replacement of everything you removed. Out back you will have to transfer a rubber mount from the shock shaft to the new coilover shock (see photos) other than that the rear coilovers are a direct replacement of everything you removed. The rear spring is mounted with the wider coil wind down with the narrow coil wind up. The spring adjuster sits on top of the new spring (see photos).

Wheel Test Fit


Not that a hybrid needs a wide wheel nor tire (actually defeats the purpose being more rolling resistance) we still wanted to see what we could fit on the car before any fender modification were required. End result was a 18×9 front and rear with a 245/35/18. The offsets did have to be staggered as the inner suspension clearance on the front is greater than on the rear. Only way to avoid this for a rotatable setup would be a 18×8.5 or narrower wheel all the way around.
