Does anyone have a download for the older 203 software? This 208 software is not nearly as good in 12th scale as 203 was.

I have to agree 203 is better for 12th scale, tried both software, 208 seems to have smoother feel for driving but on the medium to high traction track just dont have the bottom end that I want.

Anyone had experienced midrange is flat on both software or maybe its my RS speedy having problem:eek:

My car feels just as you describe. It always feels like I am over-geared or don't have the timing coming in soon enough. The turbo never really feels like it is coming on until i get to a long short chute or the straight away. The 203 launched out of the corners where this takes time to spool.

To test my low end rpm theory I tried 5k start and 3k start, the 3k felt significantly better so I am guessing that a 1700 start rpm or somewhere in that range will be the ticket. (just as I used to run on 203 when it had much more bottom end)

I tried 208 with end rpm 4k with 19xx start(lowest I can chose), it spools up quicker but motor get hot and you'll notice the timing has kicks in at good RPM but ends too early.

To do it properly would require a jig and a mill to make sure you don't affect caster and/or camber as you remove material. This is NOT a job most racers have the appropriate equipment for.

Note that IRS may have discontinued the modified AE arms they were doing, but have done so because they have released their own arm they themselves designed and are molding. Instead of the marginal gain seen by modifying the AE arms (they only "lower" it 1/16") the new IRS lower arms go WAY lower. You can run the front tires right down to the rims if that's what you want to do.

These new arms are EXCELLENT pieces, but I STRONGLY recommend purchasing a 8-32 RH tap (about $5-6) and properly cutting threads into these rather than mashing screws through them to make threads. The design is very good but creates a stress riser where the upper arm mount is let into the lower arm. I've seen these arms crack along these risers when threaded with a screw...I've never seen one crack that has been properly tapped.

Had to search way back to 2008 for this one!
Dusting off the 12L3 and having trouble getting the front up to 3mm.
Are the IRS arms being discussed here part #4221 ? The IRS site and sites selling them don't mention that these are lower to the chassis.

Thanks.

The cut-down AE arms are being made by BMI Racing (contact details on their website) and are still the best option to get the ride-height you want ;) HTH :)

so it seems that 203 is better for the 12th. I am running 17.5. Does anyone have some good settings and rollout for a track that is 70x35?
