    Depends on how you lower it.

    Keep an eye on pinion angle if you keep that where it needs to be and don't lower the front mounting point it will hit the tires harder..mine always spins if I hit them too hard. but remember lowering the rear will help it transfer weight easier..always a plus.

    That is a good way to do it since you will have plenty of adjustability when you get done. Just remember to check and if needed reset your pinion angle to get it back where it needs to be...too much breaks u-joints and destroys driveshafts and transmissions..

    Huh?

    and don't lower the front mounting point it will hit the tires harder..mine always spins if I hit them too hard. but remember lowering the rear will help it transfer weight easier..always a plus.
    How?
    If you lower the body it is attached to the frame in most cars. That means the frame is also lowed which will lower the ladder bar front mounting location. That change will absolutely NOT Hit the tires harder. It will hit the tires softer. Think about it, or plot it out if you need to.

    You are lowering the point of Instant Center. You are lowering the actual Center of Gravity. You are even slightly lowering what some call the squat/no-squat line.

    Lowering the rear of a car also does not improve weight transfer. That is something we thought back in the early 1960's. We raised the front and we lowered the rears. Doesn't work. You will not see one serious working car at the track that is set up like this.

    Now back to the question and I do agree with checking and re-adjusting your pinion angle.

    If you car is like most cars I have seen with lader bars, lowering it might help it. Most I have seen have too much monkey motion going on.

    You are right about hitting the tires harder..it will soften the hit (apoligize :wink: ) But I still think a car that is level or even just below level will transfer weight easier...
