70K miles e90 for autoX and HPDE?

[bga23]

I’m looking to buy an e90 for some autoXing and HPDE and I’ve found a 2008 that is interesting but it has 70K miles. I don’t think I’ve ever owned a car with that many miles. Should I not worry about the odometer if it passes the PPI or keep looking for a lower mileage one?

Rod bearings haven’t been done yet, which isn’t a deal breaker for me, I can always have them done or not.

Do the rod bearings as a preventative measure with the engine mounts at the same time.

Throw some decent coilovers on there (after 70k miles the stock will be tired anyway), sticky tires, and depending on your budget either pads/fluid or a BBK and you have a very respectable little track chariot regardless of mileage.

THIS. 100%.

There's several 100k+ miles e90 track cars rolling around, I would say do the rod bearings and go for it!

E9x M3 was made relevant again by the SCCA. It is now the car to have in F-street. Check this years field at nationals lol... and look at the times an M3 can put down in basically stock form. They are great cars and prices are getting more affordable finally. Bearings are cheap if you can do the labor yourself.

My car has been tracked from about 70k to 163k miles. Just now doing rod bearings (not necessarily normal - definitely not a recommendation). The only parts I can think of that "wore out" due to mileage were the engine mounts. Replaced them with delrin, I would recommend at least upgrading to soft poly whenever you do it (it's recommended to do it when you get bearings done since you have such easy access).

Edit:
And definitely agree with the others. Bearings and coilovers. And don't be afraid to stay with the stock brake system with a good set of full track pads. The OEM brakes are very good despite not having 64 pistons or whatever

I have been running an E90M3 in SCCA T1 for the last year and half. They can also be run in T2/T3 as well.

Bought the car with 90K on it, built it to T1 and away we go. The car is durable, but heavy, invest in good pads. You can keep the stock brake set up, grab a good suspension and send it.

I'm at 146,000 miles and running Roebling Road next weekend. If the motor is good on the car you are thinking about, then there should be no problem.
