Are Strut Tower Reinforcement Plates needed?
I'm about to buy some TC kline coilovers 400/700 and start seeing a lot more track days with my 128i. If I don't get the reinforcement plates is there a risk of my strut towers deforming?
They seem like a PITA to install so I'd like to avoid them unless it's an issue with the E82. |

Turner sells slip-on style plates that sandwich between the strut mount and the chassis. It can't hurt. These cars aren't as bad as old BMWs, but I have personally seen two E9x cars with deformed towers.

The only strut tower reinforcement for the E82 I can find on Turners website claim they have to be welded to the underside of the strut tower.

Turner's own e8x/9x camber plates have a large flat surface area against the bottom of the strut tower that they claim is better against strut tower deformation. Many other brands have a small narrow ring touching the tower.
I have them, however, they sort of fit poorly at max negative camber squeezing against some of the underbody sealing material in the corner of the strut tower.

Not entirely sure how anything that isn't welded in would help.

Is deformation actually happening to people who regularly track their cars or is it rare enough that I should not be worried about it?
I'm not planning on rally crossing the car, but I'd like to be able to take any curb on track at speed without a worry. |

I'd be more concerned about the rear struts pushing through their rubber mounts and into the trunk. I have 16k (1000lb) rear springs and haven't had an issue if that helps at all (Monroe rubber shock mounts)... |

I bought reinforcement plates from bimmerworld I think they were $15ish a piece they slip on the top of the strut had no issues with them.
I'm running ohlins with vorschlag plates. |
