Well, i'd probably invest more in actual tracking and track wearables like tires & pads, then in modding out car. Imho "driver experience mod" cuts down laptimes most of any car mods . Seen also cases where one invests hell of a lot to make car "track ready" in his eyes .. and never actually go to track , while there are plenty old beaters close to stock in trackday. Including taxis & delivery vans, lol Quemadillo: in your case i'd first go for a bit more minimal approach. Get parts for performance alignment (eg. for front: SPC 81305 camberbolt set (optionally also Whiteline KCA416 camberbolt set), PED-580096 top mounts, Powerflex front LCA bushings PFF69-801G, for rear some from cheaper adjustable aftermarket LCAs (eg. stock-alike stamped steel clones like from SPC/Whiteline/Eibach)) and then dial performance alignment better fit for track. +more track oriented pads that will work better even at higher temps. (btw, the more track specialized, the more pads may have issues with off track daily driving use, like squaling noise/dust/extra rotor wear/worse cold stops, thus imho preferable approach is to have two pad sets, one for daily driving, another - for trackday, and switch between pad sets according use, to have best of both and to not suffer deficiencies of neither). If moving up for even grippier tires, if going for even longer track sessions, then i'd think of BBK. (but not needed for me, as due my age, i get tired some even with 15min sessions, after that 100% concentration starts to drop, thus prefering after that to drive back to cool brakes, drink coffee, smoke cigarette :), with no felt wish to keep driving non-stop 20-30min long no matter what. And only then at some point in future considering aftermarket coilovers. Not sure if some like KW ClubSport ones, as imho those are too expensive, and may compromise comfort for dual-used also daily driven car, and extra adjustments also mean ability to adjust/dial wrong, and unless one drives each lap very consistently, it is hard to properly test/evaluate changes to dial better, as one might not know, if logged lap time was from suspension adjustment, or from doing less costly mistakes in that session . Coilovers by themselves don't improve times that much. And are not requirement for camber adjustment.

Even on stock primacies stock brake pads are a bit insufficient imho. So i'd change pads & fluid anyway. On primacies with rbf600 & ds2500 fade started to appear if at session i kept driving after 15min. Then again, brake fade isn't something catastrophic. Usually doesn't happen suddenly like on/off switch, but at one point starts to appear and increase, signaling driver that it's time to slow down pace and go for brake cooling lap, and in next session drive for minute or two less (with same brake usage intensity).
