EDITED (I was on my phone and driving earlier. lol)JScheier said:darreng505 said:Can you elaborate on this please? I have around a 1.5-1.8" drop and have my adj. LCA's mounted in the lowest hole of my BMR relo brackets. This has greatly improved rear end stability during high speed braking (especially on declining straights).
I do not consider 1.5" an extreme drop. 2" or greater, yes, extreme, and then you run into other issues (pinion angle, damper range of movement & lack of travel, roll centers, instant center, etc. Will moving the arms from the OEM location to 'a' lower location on the axle increase rear stability when lowering the rear of the car 1.5", yes. Will moving them to the lowest hole with this drop help more, I'm not seeing it.
I see it however. But I recognize a lot depends on the driver, and other car suspension changes, etc. Generally, the angle of the LCA with respect to the chassis and rear axle is "one" determining factor in the affect of traction and axle stability. So it shouldn't be a subjective thing.
At VIR earlier this month I tested my adj. LCA's in the bottom and middle hole (they are not that far apart actually) on a wet track (VIR full) and the second day on a dry track (VIR grand). I noticed slightly less traction in the middle hole (compared to the bottom), but I only based that on two occurrences: 1) The rear end got loose coming through/down turn 10 on VIR full and 2) Coming out of turn 12 on the back stretch, I lost traction pressing the accelerating. Both times in the middle hole (and in the rain). But it's not really a scientific experiment and there are too many variables to conclude anything from my situation due to track conditions.
However, on dry track, in either the middle or bottom hole, the high speed braking situation I had prior to the new LCA's and relo brackets was gone (see thread https://trackmustangsonline.com/boss-302-technical-forum/heavy-braking-situation/ ) so I know that at least in the lowest hole configuration it improves brake handling significantly. So much so, that I'm amazed how the car handles now compared to before. As a previous Porsche owner, I feel its now "in the game".
My curiosity with your earlier post was with regards to this comment:
That lower location is too low for a 1.5" drop. For short term use, it will be fine (IE: safe).
I am still new compared to you and others here with all this, so I want to know what safety issues might the lowest hole pose to a lowered car? And why is it 'too low'?
Thanks for your time btw!
