OK so....
Front:
30wt
3A w/o limiter
unthread 3 turns
light yellow spring
middle on tower
outside on arm
link @ middle on bulkhead, inside on arm w/ 2mm washer
Rear:
30wt
2C w/o limiter
silver stock/kit springs
outside on tower
inside on arm
link @ middle on tower side, outside on arm w/ 2mm under both sides
hubs forward
hubs down (pin through TOP hole, closest to axle)
Misc:
13.5ss novak
LRP Sphere comp ESC
maxamps 4000mah 7.4 lipo
1/2oz under steering rack
1/2oz in webbing directly behind the front tower
1/2oz in webbing directly next to servo
1/2oz against rear wall directly under rear tower
1/2oz in webbing directly next to rear tower
1/4oz on top of gear box
and by 1/2oz I mean, ONE 1/4oz brick on each side, across from eachother
Tires:
Front:
pink taper pin front w/ stock foam
Rear:
pink taper pin rear w/ bomb 1 on proline axle
Notes:
This setup has a TON of off power steering, so beware when you let off the gas completely, it's gonna turn, not get loose....TURN. I have yet to experience my car getting lose or washy under any circumstances with this setup and I put about 1 continuous hour on it last night with a pair of lipos.
It doesn't wash out, it just cuts and goes wherever it's pointed. For those of you who like to "push" a car through a corner, you probably won't like this setup...but for those of you like me, who like a car to ROTATE and you have to "turn" the car through the corner, then you're going to high-five me!lol
Basically, you have to be steering the car constantly, because it cuts and goes HARD, be ready is all I'm saying....but if you can get used to the quickness, I think you'll like it

I tried changing the rear shock position & spring as suggested.
Noticed a lot more “rotation”.
But I think the set-up is the ticket for high grip blue groove track.
In other conditions when grip is not as high, it just makes the rear "nervous", a little harder to control.
It’s certainly a tuning option, dependent on track conditions.

the best word to use to describe this rear end is "ROTATION"....ease off the gas, turn the wheel and hold on! But it doesn't slide, it, rotates. If you let off the gas too fast and too much, it might over steer, I've found that you have to consciously roll on and roll off the gas to have this setup be effective for you. The rear end is super planted though, really an interesting find, I like it.
Personally, I would like a hair less INSTANT grab in the front, so, i'm going to experiment with a few shim placements up front, maybe even go to a longer front link to calm it down. But the rear shock location is really where it's at for me!

I’ve broken 2 items.
1. Front (stock) turnbuckle . It was bent almost 30-deg and it wasn’t a bad crash![weird](https://www.rctech.net/forum/classic_images/smilies/weird.gif)
I straightened it and continued racing. In the next race, it finally broke and the fracture was, unsurprisingly, the exact same spot.
2. Rear hinge-pin holder in the rear (that holds the back plate). Again, it wasn’t a big hit. Car came to a cruise after the race. Got tapped from the rear. It must have been at an angle, enough to sheer it off. Fracture was near 1 of the screw threads.
