understood,

but I would like to know if anyone is using them and how do they think they compare to the AE springs

If it helps any, I have had a bunch of people order them for all brands of cars. They seem to be becoming a very big seller for us. I designed them to enhance the handling of our car but it seems alot of people are liking them on other cars also. I have not personally tried them on other cars, just ours.

all in all, they do not collapse like the ae spring and they do seam "softer" then the AE springs. I was running 18AE and went to 20BMI. have 4 solid race days on them and they are the same length right to left. the AE springs were not even the same length out of the package.

I need a set. That has become one of my bi-weekly expenses, new front springs. I hate how you tap the front end barely hard and they your car starts hopping and is all out of wack.

So what's up with the "linear" front springs on BMI's site? Is this implying the stock AE front springs are progressive?

The AE front springs are progressive. Our springs are Linear and preset to there length so they will never collapse.

How can I get some of those springs??

Give me a buzz bro. I will get some out to you

So are the BMI kingpins larger diameter or just longer?

We do offer longer kingpins but our springs work on standard 1/12th kingpins. You will need to remove 2 of the kingpin shims but they will fit with no issues. Our kingpins are standard 1/8th diameter. The springs are a larger diameter and come with spring perches.

has there been any talk of battery companies coming out with a lipo equivilant to a 4 call pack for compeative 1/12 racing?

People talk about it all the time, no companies talk about it. Unless the voltage gets dropped to nominal 3.7v you will not see Lipo used in 12th scale. At that low voltage (single cell) most people will need to run a receiver pack. If that is the case, how much money are they saving, or how many headaches are they avoiding? Even with a 2s receiver pack, you will need a lipo regulator so that you don't kill your electronics.

With the reduced voltage comes reduced rpm, both directly related...

I like the idea of reduced maintenance in 12th scale, but not the smoke and mirrors kind of reduced maintenance. Receiver packs are just another thing to monitor all the time. This is also an issue for people that want to race World GT, as the rule set for that division is 4 cell NiMH.

with the LRP Sphere 007 you can race 4 cell without receiver battery: no problems at all even with a 4.5 in a 12th scale car.

Frans the issue isn't with the ESC it's with the reciever. The Spektrum systems are very sensitive to voltage and if it drops to low it shuts off. At 3.7v the reciever won't even run so you'll need a reciever pack. Other recievers have issues with that low of a voltage as well but the worst is probably the Spektrum.

timmay - another good point, i have a feeling that the solution lies in the world of li-ion. we will have to see what shakes loose in that feild.
