I'm really excited to try these. I've never been sold on the garden variety adjustable control arms.

Lowering the car will also reduce anti-squat. Seems like if the car were reasonably low adding this part might be a little much. But I guess it would also depend on power and spring rate.

What LCA are you talking about that has a different mount point to the chassis to change ride height? I imagine the person that raised the rear back up did so to change the handling bias, not because this mod lowered the rear more.

Read my post that you quoted... I acknowledged that there are LCA's that lower the car, but it's by changing the lower pickup point for the shock. The post I quoted specifically claimed different options where it mounts to the chassis that would alter the ride height.

Lowering the lower shock/strut mount isn't to lower the car, but put the damper back in it's designed operating range.

I don't think it was a typo, especially since he asked why changing the mounting point with this mod wouldn't also change ride height. I think he thought that the LCA actually had different mounting options to the chassis, not the shock mounting points.

It is true that antisquat reduces body movement under throttle, but it does so by putting some of the torque into binding up the suspension (putting force into the trailing arm and subframe rather than letting the spring/damper absorb the weight transfer). Basically antis are the same as roll centers, but drawn in the side view instead of front view. Nonetheless, weight will transfer given an acceleration. By having the spring/damper take the weight, it actually slows down the transfer (both applying and releasing the throttle) and will thus calm lift-off over the same way it lets the driver apply the throttle earlier. ... Keep in mind... Like roll centers and almost everything else suspension wise, one cant say "antis are bad," it's just another lever to pull in finding your desired suspension balance. |

Have any of you Northern Hemisphere chaps tried this yet?
I am keen to hear your thoughts.. |

320 USD for a pair of brackets? Rather spend 50 on the whiteline positive traction kit.
NE Ohio represent. |

My car is at stock ride height, so the effect on anti dive will be at the maximum. I run Bilstein HD (B6) dampers. I have the 20 mm Whiteline front bar. I fit 2017 rear springs. I fit the Whiteline rear subframe bushing inserts and transmission mount insert. I run the Edelbrock eForce supercharger on 91 octane Shell V Power, all we can get around here. With winter tires there is no longer any wheel hop. We shall see if this also is the case when the summer tires go on. The transition from grip to powerslide is no longer of the tank slapper variety. I have not yet tested the effect of an abrupt lift off, I tend not to drive that way. I expect the tuck in to be much more controlled but we shall see. I highly recommend this modification. Subaru should redesign the trailing arm pickup point to drop it the same amount. I predict the benefit will be slightly less for a lowered car since lowering the car already reduces the effect of the anti squat geometry. The benefit is most for stock ride height. |

The Whiteline bushing inserts are a no brainer, every BRZ/86 should have at least a set of rear subframe bushing inserts. The subframe moves around a lot especially if you fit better tires. http://www.ft86speedfactory.com/whit...l#.WN7RN9TOef0 If you are really looking for stability at the rear Whiteline also makes track rated bushing replacements, as do other makers. These are different in function from the MCA brackets. |
