you do not have a track car at the moment, it is a straight line machine

410s are not track gears...unless you have overdrive or a 7500 rpm redline

Manual 16:1 steering with Tuff Wheel replica - you need a good steering box and the k frame boxed in as MAJOR flex takes place where the box mounts.

It is a misstatement that these cars will not have rack feel steering - I built a 70 Charger R/T that has amazing steering feel. Track car. Eats SRT Challengers driven by talented drivers. No slop in this ride. See pic, taken at "toe of the boot" at the glen Weld weld weld

Aluminum wheels 15x8 +0mm rear and 15x7 +10mm front
255/60/15 rear Radial T/As (ugh)
225/60/15 front Radial T/As (ugh).
NO NO NO

Tire and wheel sizes should be the same.
Ride height is wrong, back of car is sky high,
Poor tire choice, not sure about the wheels, need to see pics

Stock front sway bar, no rear sway bar
You need a 1 inch front bar & 3/4 rear
This is all a waste of time till you fix this

QA1 Upper and Lower control arms
QA1 lower arms have not been road course tested best i know or tested on a press against a stock arm - i am not sure if i would trust them at 130 mph under duress.

Sway-A-Way 1.14" torsion bars
Hotchkis lowering leaf springs
Fox 1.5 shocks (Hotchkis)
Mancini Camber spacers
All good here
