Yeah, i saw it for the first time yesterday when you brought it to the track. I took alot of heat for that back when i first developed my rear suspension. I have never seen it in person. Now i have and was like, oh hell no. I took heat for years but at least now i know. It was nice meeting you yesterday bro.

On a Prostrut frontend, you also change the rollcenter by changing rideheight. But you also change it when adjusting camber.

I have to admit that the coolest thing about running a BMI car is that its designed by someone who UNDERSTANDS suspension geometry. That knowledge is incorporated into the cars' design, and its performance is proven at the track by regular joes.
Not to mention the fact that anyone of us regular joes can get ahold of Jason at any time. Who else can boast that fact?

and you right, a car that anybody can get to work. I started 1/12th with different car (no names mentioned) struggled for over a year, swoped to BMI and straight away I was on pace with the top boys.

Simple tire wear (since we use foams) changes roll center as does shimming a strut arm for ride height changes because in both cases the height of the lower arm changes in relation to the ground. Not to mention because the lower arm is fixed the roll center moves more left to right instead of just up and down.
The new BMI front end is by far the easiest front end I have ever set up. No longer is there an issue having to machine or shim one arm to compensate for molds that have been used too long and are worn out. It is super easy to make sure the left side and right side of the chassis are at their proper heights.

Here's mine...
Up until now it is only build out of the box, the electronics will go in soon and hopefully next week when the track opens it will get it's first ride...

LRP SXX v.2 (part #80905)......1/12th- 10.5
MODE.1- #1
MODE.2- #5
MODE.3- #3
MODE.4- #0
With the speedo, there's no need for a rx pack. It has twin BEC's inside.

I run mine with a Tekin RS and a Losi 180mah LiPo pack for the receiver pack.

Here is a short article on suspension designs to help see the differences between suspension systems. This will help educate people with fact instead of nonsense that people have a tendancy to make up all on there own.
