I have used many different brands( QUA1, CE, Lakewood,Hurst and Koni coil overs ) and types of front shocks on different A bodys, none of them went into the nines, all low to high ten second cars.The ones I like the best so far are the Koni SPA reasonably prived and they work excellent on all of the tracks I have ran my Duster, from good to bad with no adjustments
