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.

I would think that it would be too easy to bind up the rear axle with that design. You'd need a very good set of calipers to make sure that both sides were EXACTLY the same height.

That is simply awesome! Thanks for cutting that idea out of your posts on '1/12 forum' and furthering it over here. Go Team BMI!

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.

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.

you're presuming that the current rideheight adjusters that we use now are super accurate... well maybe they are... besides, who doesn't own a set of calipers , if you've been racing onroad for almost any perior of time you most likely have some??

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

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.

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 used to have a spreadsheet with 2 simple equations in it, one for the front and one for the rear. All I had to do was input the current tire diameter and it would output the sized ride height adapter I needed. It worked pretty good and would usually get me to with in .5mm of what I needed so it really cut out a lot of the guess work. Problem was I usually didn't have my computer with me so I kept forgetting to use it. Now that I bring one with me most of the time for my RS and carry a smart phone which could probably handle it too it may be time to bring it back.

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)

or make something

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.
