Why Choose the ST XTA Plus 3 Coilover Kit

The XTA Plus 3 is one of the best-value coilovers available for the F2X platform, using proven KW Automotive technology packaged with ST’s durable materials and accessible pricing. The three-way adjustability allows you to fine-tune compression for bumps and kerbs separately from body control, while the rebound adjuster lets you tailor how the car settles through corners.

The included camber-adjustable aluminium top mounts deliver the precision and alignment flexibility needed for modern performance tyres. The result is a suspension setup that feels significantly more responsive and confidence-inspiring than OEM, without stepping into full motorsport damping.

For M135i, M140i, M235i and M240i owners who want a serious fast-road and track-ready setup, the XTA Plus 3 is an exceptional upgrade.

Installing / Notes

  • Professional installation, alignment and corner balance are strongly recommended.

  • Top mounts may increase NVH slightly compared to OEM rubber mounts.

  • Check wheel and tyre clearance when using aggressive camber or low ride heights.

  • All adjustment points are accessible once installed.

Great center piece for my gaming room

It’s quite large, but you can display a lot of your cool collectibles on it. It arrives in a nicely packaged box with instructions, although I found the instructions to be quite basic. Most people should be able to figure it out. Instead of following the instructions, I recommend forming the honeycomb structure on one side and then attaching it to your wall. Drill holes through the holes in the honeycomb, ensuring everything is level. Once the entire unit is assembled, one person can hang it on the wall. However, I suggest having a building partner. I attempted it alone and was straining my core while reaching on a ladder, which was probably not the wisest idea. The build quality appears to be very good, and I believe it will last for many years. The LED light colors are nice, though not as good as those on a razor, but they’re not bad for a third-party product. There are plenty of screws to install, with a couple of extra. Just for reference my computer screen in the g9 57 inch that’s how big this shelf unit is. Holds up to 120 lbs

Will probably buy another one!

Looks great, LED strip is a nice touch. The unit is relatively lightweight while still being quite sturdy. There were a lot of parts and it took some time to assemble, but the instructions were very clear - just step-by-step drawings but everything was labeled clearly. I was pleasantly surprised that the hardware that is used to put it together is better than you’ll often find with low-cost shelving and furniture too, which gives you confidence while assembling. Just don’t over-tighten anything to avoid cracking or stripping the parts.

Nice product, wall mounting could be easier
Size: 7.9"D x 39.4"W x 34.3"H, Color: White
Easy to put together, nice finish. Missing a star cause mounting it to the wall is a lil more difficult than it should be. I would never use the wall anchors to mount this
