Roughly 80,000 miles, Preventative Maintenance Advice
Hello gentlemen,
I recently passed the 80k milestone on my 2005 RX-8 and have been wondering where to really go from here. I love this car and want it to last, and while I acquired this car in December, I haven't even driven it much since the weather was rough. Since my driving of the vehicle has picked up, here's short list of what I've done in my first 5k miles:
-Upgraded to R3 starter
-New MSD coils, wires
-Fresh set of iridium sparks
-New battery
-Midpiped exhaust with casper O2 simulator
-Began premixing 5oz per full tank with Idemitsu
-Fresh Redline MT-90 in trans
-Fresh Redline 75W90 in differential
I'm not sure what to prioritize next for preventative maintenance on a semi-limited budget. Much of the advice on the forum suggests that at 90k (close to where I'm at) one should:
- Replace coolant bottle
- Replace radiator hoses
- Replace radiator
- Replace front O2 sensor
- Replace motor mounts
- Inspect clutch pedal assembly for flex / weld breaks
In the pooled experience of the users here, which of these should be priority number 1 for my situation? Thanks a ton for the guidance.

The O2 sensor, motor mounts and clutch pedal can be examined to see if you need replacement. They could be fine.
The rad, bottle and hoses give no warning signs before they let go, so that should be priority. Of those, I would put the hoses at the top. Then the rad. Then the bottle.

This car was my father's for a while before it was mine, unfortunately. He claims he got it tested at a Mazda dealership back in Cleveland and she pulled 7.3's-7.5's for each rotor, which isn't terrible for the point she's at. This was almost a year ago now, and I would probably be doing myself a favor if I got a fresh test.

I've seen this bad boy in action and have wanted one for a long time now.

I just don't have $300 to pony up when I'm trying to save for a rainy day with the 8.

It's been a while, but back in May 2016 Montrose Mazda of Cleveland wanted $250. They don't have a very good reputation tho from what I hear so that may be high.
I've heard that argument before. I'm just not sure how I'd even "advertise" haha!

Dude, $250 to test once or $350 to test as many times as you like. Seems like a no-brainer.
Advertise on the regional forums here. Bring it with you when you go to autocross or trackday events (you are doing these, right?).

I most likely will get a RCT-V5 closer to July after my next co-op begins.
That's some stellar info to have, thank you. I will look into it.

I'd think long and hard before extrapolating the small sample of "what's been said on the forums" to the RX-8 universe as a whole. Anyone who's taken even an introductory statistics course could tell you that.

Well, as somebody who has been through plenty of probability and statistics, it's called a sample of a population. However, nowhere do I claim that the sample here is 100% reflected in the total RX-8 population. The 100k+ mileage is thread is even proof enough that plenty of these cars do make it over the hump. This is just something I personally feel I need to be wary of given my car situation.
