Engine Oil and Filter

 

 

Magic number for me is three.

 

Diff - every 6 months so about 4-5 track days

Brake - every 6 months so about 4-5 track days

Trans - every 6 months so about 4-5 track days

Engine Oil and Filter - every trackday or every second if I'm lazy

 

diff - 6 months

brake fluid - bleed after every track day. Flush every other track weekend.

trans - 6 months

engine oil/filter - every other track weekend.

 

Here are all the parts I keep track of.

Diff- Every 4 track days or 4K street miles (torque 80-95)

Brake- Every 4 track days (torco, castrol srf, brembi htc4)

Trans- Every 2 track days (Lightweight Shockproof, OEM)

Engine Oil and Filter- Every 2 track days, or 2k street miles (5-40 Rotella, 5-40 Mobil 1)

Clutch- Every 2 track days, or 2k street miles (torco, castrol srf, brembi htc4)

Rear wheel bearings- Every 2 years or 20+ track days. (OEM)

Caliper rebuild every 1-2 years (OEM)

Valve Check every year


All balljoints, bushings, tierods etc, inspected before every event,

 

Diff - Never. That shit stinks.

Brake - Ideally bleed em before every event, but more like every 2nd or 3rd weekend. Castrol SRF is expensive.

Trans - Every year. I already swapped it once after GTA, and it didn't change anything as far as feel and looked brand new coming out. $40 wasted.

Engine Oil and Filter - When I'm at the parts store and I see a good oil/filter change deal, and I have free time to do it. Maybe once every 4th or 5th weekend.

 

Very technical and well thought out.

 

Thanks bro. To qualify it, I am pretty slow, and I don't run full 20 minute sessions, and only run 5 sessions a weekend on average.

 

Diff - 6-ish? I dunno. Whenever I remember.

Brake - Bleed every track day, flush with new pads.

Trans - Whenever I start feeling a notchier shift, or experience grinds. Usually twice a year.

Engine Oil and Filter - Every other track day like clockwork. I never skimp on this.
