Has motor swap and coilovers as major changes

rb20det (turbo)
bc coilovers
brake swap front and rear both disc both bigger than stock
no tune
No mods to engine
no CAI
front and rear control arms are not stock, both are aftermarket
225/16 tires
2wd

besides the motor swap and brake swap its a relatively mild car upgrade wise.
what would be the best class? I am a novice to auto x and looking forward to learning to drive better.

I believe you would have your choice of XB or XS class depending on how much she weighs. Your tires should be 200Tw or higher.
