New 98 boxster and getting it ready to track

[jonasjmac]

So I'm picking up a 98 boxster to track/hpde and questions on what do to get it track ready as it is stock, other than M030 suspension upgrade. My two major focuses are saving myself and the engine so safety and engine oil mods.
Safety wise I found a Brey Krause extension and hardtop. I am looking at seats with harnesses. I'm 6'2" 200 and looking into sparco evo seats or other recommendations.
Engine wise-which parts are most important to keep oil starvation on track?
Thanks!
