bouncy ride

i just installed my coilover sleeves, which I know that I should have gotten full coilover system-but I a poor college student. Anyways the ride is really bumpy when I go over rolling bumps like on the freeway. The whole car just bumps horribly over the rollers. If I cut the bump stops down(about 50%), I have a feeling that it is maybe riding on the bump stops. any ways any info will help

Quist

P.S. I am getting new shocks in a little bit but I dont have the funds right now
