Wheelie question

First thing i did was install a taller front tire for ground clearance and got a different oil pan
( 8 qt Milodon) as she killed the moroso pan on her first big wheelie. I boxed in the lower control arms and welded plates on the k frame around the lower control arm pins. Inner and outer tie rods are 11/16th with PST steel adjusting sleeves. RMS upper arms and strut rods. I run a 2 inch tall bump stop on the lower arm to prevent bottom out on the track. She has pulled hundreds of wheelies and has never broke anything. We have a front /rear weight bias set at 51.7 front and 48.3 rear.
