All the best, Chris.

PS, you got PM.
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.

That is true. The Pro Strut front end also has a shorter upper arm than the L4 strut front end so unless you run the long upper arm kit, you have more roll center change during suspension compression due to increased camber gain.

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?

Jason Rocks
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.

BMI works

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.

LRP SXX v.2 (part #80905)......1/12th- 13.5- NO BOOST

MODE.1- #1
MODE.2- #6
MODE.3- #0 (boost disabled)
MODE.4- #5

With the speedo, there's no need for a rx pack. It has twin BEC's inside.

Good choice!

Last time I drive on GM 90V2 with 13.5T/X11 engine and with booster (the cheap one) and for me, you don't need rx battery it is one thing less for charging.

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.
