for everyone running modified or open, how would one get better traction coming out of slow corner hairpins. At the moment the rear end if i pin it about medium it just bits in and wants to spin.
Currently running lipo in standard configuration down centreline of chassis. already on softer springs, dampening and tires, Would i just be best to go to the transverse setup to save time, more weight in the rear?
Track just been built indoor asphalt, high bite and grip getting better as more people run.

Just got back from the US Indoor Champs.
They ran 1/12 17.5 and 1/12 "Masters" all together this year.
I Qual. 4th and finished 6th overall.
The 6th place finish was the highest "Masters" finish.
Here's a pic of my XTi as I ran it.

As a side note: The layout was a sweeper on and sweeper off. But it was built in a 80 x 40 box. This made the straight short (inside wall was 52') but the sweepers accented the need for bottom end to accelerate (the on sweeper) and power thru a corner the off sweeper).

This maybe a dumb question, so be nice
Trying to figure out mad tire wear on the inside fronts on my Xti. running 5degree dynamic caster, 1 degree neg camber.
Pic shows new tire on car and how outside is lifting on full lock left or right. Worn tire shown next to it.
Also pic of my front end. Anything obvious ?

How much static camber are you running?
You will always get camber gain on lock. Normally you should add or reduce camber to get the tyre to wear flat. Looking at those pics it looks as though you have quite a bit. I would set it back to 1 deg and adjust from there.

Maybe its just the angle of the pic, but that looks like a good bit more than 1deg of camber.... more along the lines of 2deg or so.
But regardless of the amount of camber, my other question is whether you are actually driving with that much steering throw? ie: lock to physical lock? If so, that could be causing the coning even if you are running only 1deg camber. Positive caster angle(static caster, not reactive) causes an increase in camber gain at the outside wheel while it is turned. The more it is turned, the more camber is gained... So it is possible that you are introducing too much camber via the amount of steering throw.
Edit: Again, this may be the angle of the pic or just my eyesight failing me... but it also looks like the inside of your front upper arms are angled to the outside pretty substantially?

Those aluminum caster blocks do have a tendency to bend...from that picture angle they do look like they may have bent. I would double check those...plus what everyone else suggested.
