I'm thingking to get coilovers for my 2010 is250 RWD w / 18x8.5 F & 18x9.5 R . Now I'm on H&R springs which lowered 1.5" F & 0.8 R .
I like the front lowered with a finger gap between tire & fender but the rear still lil to high ( 11/2-2 fingers gap ) .
1 : If i want to buy the BCR coilovers , just buy as is or Do i need to get stiffer springs rate ?
2 : I dont how how much drop it will be if i want a finger gap between so Do i need FRONT & REAR camber kit ?

Probably going that low. I have SPC rear camber kit arms (brand new) and maybe selling my SPC front ball joints (brand new) that adjusts camber to 1.5 degrees. PM me if interested I'm in socal

You shouldn't need camber arms at 2“ lowered, unless you're planning to run negative camber.

As for springs, i reco that you upgrade bc springs with swift springs. Stock spring rates are fine.

Agreed upgrade to swift springs with the BC.

(no swift springs for me) I went with 14k front / 10k rear.... but a) I have an AWD, which weighs about 200lbs more in the front b) the standard rates of 10k/8k are said to be a bit too soft by some, but others like it!

Circuit motorsports (a vendor on here) seems to recommend 12k/10k as a good setup.

As for camber, if you're not lowering that much you should be good without.
Its unique for everyone: depends on the final resting height, wheel offsets, etc.

14k front/10k rear swift springs FA500 coils are perfect!!!
