Help with lifting 2007 Tundra

Hello I am helping my son lift his 2007 Tundra to fit new 33x12.50x18 tires. Yesterday we installed new KSP 3" front and2" real leveling kit. We are still using the factory coil overs. However the more and more I read about these "hockey pucks" the more worried I become. He currently is running BFG 32x10.50x18 tires and with the new lift, they barely fit. So I am worried that the new tires are going to rub as well. Would we benefit by adding a pair of Bilstein 5100s for the front along with the "hockey pucks"? Or should we remove the spacers all together and just purchase the shocks? Since this is a 2WD truck it really never goes off road, so this is for looks and fitment only. Any help is appreciated.

 

I have never heard of KSP, but spacer kits are fine for street use. The most common are the ReadyLift kits. I have their 3/2 kit in mine with 285/70/18's but I also run a 0 offset. The Bilsteins won't do anything with already having the spacers installed. Your issue with the rubbing is the wheel offset. What wheels are on it?
