Update: I have purchased a set of RCE yellows per strong recommendations of this forum. Thanks so much guys, I'm sure I'll love them!

A followup question\: What camber should I aim for when getting an alignment? I want a comfortable ride and only daily drive the car(city, highway, and country roads), no track. I also plan on getting 20mm and 25mm spacers for the front and rear, respectively. Does extending the wheel from the hub affect what camber I should aim for?

Any recommendations for front crash bolts? I was looking at some on Amazon and most had mixed reviews.

No track? Hmm, i'd try usual "0.5" less in rear, but lower overall camber.
eg. -1 front, -0.5 rear, or -1.5 front, -1 rear. Probably former, as you haven't mentioned purchase of rear LCA, which is needed to make camber adjustable in rear.
Zero toe front, 0.1 toe in rear. Or zero toe all around, if you rarely push much on roads/in curves. (toe-in can add some stability when flooring accel, but it also increases tire wear more then camber does).

Extending wheel doesn't affect camber. Wheel will stay at same angle to road. Scrub radius will change with spacers, thus you may expect a bit heavier steering.

Get camberbolts from ft86speedfactory. Or look up which models they sell and search those elsewhere, to simplify choice. SPC 81305 for lower strut hole, Whiteline KCA416 for upper. With camber upto -1 i guess bolt set for just one hole should be sufficient. Need both for up/low, if want neg. camber >2.

I have -1.5* in the front with camber bolts and -1.0* in the rear with SPC LCA's.

IIRC a 20mm drop in the rear will likely give you more than -1* camber. If you don't intend on adding any rear camber adjustment it would be a good idea to set the front camber at least just as high as the rear to -0.5* more than.

Oh right. Somehow missed RCE yellow bit. Indeed, one will naturally get negative camber when lowering with suspension like in our cars. Then maybe one can get with just camberbolts for front for "street camber", w/o buying rear LCAs.

I suppose if the OP didnt mind the understeer, then no addition of camber in the front would be fine too.
