So Jason, if you wanted to be more bold in your new car... do some adjustible ride height that doesnt require shims, like this:
Thats an oval car from MC/RC, but they have adjustible front and rear suspension that requires no inserts. Just a screw driver. Pretty hot stuff, if it can be done light enough and sturdy enough.

For the club racer especially, putting the concept in play for 1/12th On-Road just speaks for itself. Setup maintenance for dummies. Ride Height Gauge, wrench, 2 sets of tires in your pit box and the perfect ride height every time you hit the track. Quick, Easy, Precise - enough said.

True, but isnt that the case with so much on these 1/12ths... I know I use my calipers for most adjustments I make on these cars. Also keep in mind that the plastic spacers have some variance in them also.

That's why I don't use plastic spacers I use the BMI machined aluminum spacers

Please don't try something like that. Like someone else said already, it will be too difficult to get perfect ride height left and right and who know, maybe the screw will get loose or something cause of vibrations and during driving one side will go down? Just stay with the IRS ride height adjusters. It is KISS so good for our application.
I dont think the challenge for perfect ride height is that hard with the screw based setup in the Apex car. Remember that Oval racers are all about chassis setup... they focus on that FAR more than road racers (as is evident by the endless setup possibilities on those chassis, and the out of the box thinking these guys come up with). If this level of detail is functional for oval guys, I assume roadies can handle it also.

Inspecta, i gueas you mean you use the aluminium ride height spacers at the front ?
Just wondering as I could not find aluminium ride height spacers for the rear axle on the BMI site.

I do agree that the rears arent a real big deal to put inserts in. Its the fronts that suck. Its Quite labor intensive and random to get front ride height correct and something that is not quick to do. The rear is essentially one set screw you need to undo, to put in shims.

the BMI front Al spacers rock, but they are too tall for the R5 front end... once I true down the fronts to the point I like to race I can use the smallest 3mm shims BMI sells for about 2 runs, then I am on to using other various mixes of spacers. if BMI could make some nice alloy spacers that are similar to what Yokomo used to sell... that would rock (at 2, 1.5 and 1mm)

The front end im working on is sure to impress. I cant release any info yet but rest assured, it will be inovative and be easy to set up. As you know, we are not going to just remold an AE front end and claim success. We wont release anything unless its an improvement. At this time i am not sure if it will be able to be produced cheap enough to release with the car but maybe as an upgrade. I will have to see what i can do. All i can say is that it will be in typical BMI style.
