The Wheeler T1 are the same spring as ToyTec 112-620, but a different color and a bit cheaper. After the ToyTec discount, they're only about $2 difference. Shipping from Wheeler's was a little cheaper too, but we're only talking $2. Wheeler's is closer to me than ToyTec so it's generally 2 days from order to my door. I've called both companies with questions and both are friendly, knowledgeable, and helpful.
No aftermarket front bumper. (Well, not yet at least!) I'm running the Tundra Bilstein (24-261425) on the first perch in the front and the FJ Bilstein (33-187174) in the rear. They ride good. It's my DD and have no complaints.
Take this next statement with a lot of GoogleFoo...
I thought I read somewhere on here that the OME 861 would give about 6 inches of lift. If so, that would give a lot of rake with the T1's. I was thinking about running OME 890 springs, but after talking with ToyTec about their SuperFlex decided it was closer to a LC spring than the OME. From my understanding from talking with them, the OME 890 would be basically level under normal driving (ie not towing). Again, check these statements out. I could be wrong about the 861's.
As far as settling, I have no real world experience as I just put them on.
They don't feel too stiff to me. I was actually wanting a softer spring initially. Now after having driven them a bit, they're fine and I'm glad I went with them.
I'll have a better report mid-July after a trip over to Glacier.
