Hi. It might also be worth looking at your tyre prep. Also some chassis have a narrow setup window, I am not sure about the Mi5 but I know that others like the D06 and T4 setups can be generally carried between tracks. Like one of the others said, have one of the top guys take it for a few laps.

Looking at that setup, what I feel you've done is make the front too stiff so as too take away grip, then changed the rear of te car to get steering back... Which has only ended up to compound the problems. My advice is;
  • 450 in all shocks, and drill a hole in the top cap whilst your at it to vent them. I also prefer to build my shock with zero rebound, always.
  • Set droop to 3.5 in the rear, and 4.5 at the front. Never run more droop on the front than rear, car is going to do some very strange things that way.
  • 1500 - 2000 in rear diff - thicker oil will help to take away initial steering whilst give back some on power.
  • Move rear shock out one hole on the rear tower
  • 0.5mm under all lower suspension balls
  • go to 1mm shim under rear inner upper camber link ball, and nothing under the front
  • put 1mm shim on rear axle - more stable, end of.
  • put on a new set of tyres

That should get you much closer to the ball park, with a car that will probably push a little, but is consistent to drive with decent grip. Once that's settled, then look at things like the 3dink plates, springs, rear hub plates etc for extra tuning options.

Cool thanks that makes sense do you think I should go lighter on shock oil in the rear?

Honestly, start out with equal front and rear. At the moment you want to make the car safe to drive. If it has a little push, that's fine, it'll be more consistent that way, and get your confidence back. Once you've done that, start hunting for more steering.
Something else I forgot to mention is also look to change the rear arms to the 2.5 ones. The 3deg actually give a little over 3deg of toe, whereas the 2.5's are much better suited to 13.5 blinky. I actually use the 2.5's all the time on my mod car anyway...

Also, what are you doing in terms of tyre prep? And what sort of ambient? I assume that you have asked around the pits on advice of how to get the Sweep40's working? As that will also have a big effect.

You could always try posting on Martin Crisp's thread for help and in addition, give learnsetup.com a try. It's well worth it and is a great trackside aid.

you have to control the front slider inserts (U3814)

specially in front with spool and ECS they wear quickly and block the slide of bones

it results in an undriveable model and any change of setup is useless, you have just to replace the inserts

I had the same problems

Looks to me as though your car has been on ebay for 6+ days - up for sale.

have you tried the car with new inserts? I'm sure those are your problem!

however, I use both grey and black inserts, but every 2-3 days on the track I check them and if they are slightly worn I replace them immediately
