135i vs M3 Axles: Which Should I Upgrade?

Thanks for the insight! That’s a key detail many might overlook. It definitely seems like upgrading requires some planning.

Honestly, if you’re not racing your car often, sticking with the 135i axles can save you money and still provide a solid performance. It really depends on your driving style.

True, but if you enjoy track days, upgrading is a solid investment. It’s all about finding that balance.

Anyone else debating whether to just replace broken axles with the same stock ones or go for the M3? Seems like quite a few people are leaning towards the upgrade.

I think it depends on how you drive. If you’re already looking at replacing, the M3’s might save you headaches in the future.

Or you could just reinforce the stock axles and call it a day! I mean, who doesn’t love a good DIY upgrade? Plus, it saves some cash for that new turbo!

I’ve had a major issue with the axles on my 135i. They tend to clunk during hard launches. A common fix is to replace the center support bearing. Just something to keep in mind!

I can relate! My friend’s M3 had a similar issue, and replacing the axles completely did the trick. Definitely something to consider if you’re looking for a more permanent solution.

I had the same clunking noise as you both described. For the M3, the power delivery can lead to a lot of stress on the axles. I recommend regular checks and possibly upgrading to performance axles.

Preventive maintenance is key! Regularly inspect the boots and joints. A small tear can lead to bigger issues down the line for both models.

I never thought about the boots when I was upgrading my 135i’s axles. Now I’m paranoid about them! What type have you guys had the best experience with?

I’ve heard conflicting opinions about aftermarket versus OEM. Some swear by OEM for reliability, others say aftermarket can provide better performance. What do you all think?

I went with upgraded aftermarket axles designed for higher performance and they’ve held up well, even during spirited driving.

OEM is definitely reliable, but if you’re pushing higher horsepower like I am with my M3, aftermarket is the way to go. Just make sure you get a reputable brand.

It’s all about balance! Upgrading the axles might be enough for your current power level. Test them out before deciding to go full performance mode! Just ensure you regularly maintain them.

Honestly, both setups can have their quirks! I find the M3 can suffer from binding if the axles get too worn out. Always good to be cautious!

Yikes! I didn’t know that. Definitely a reason to stay on top of maintenance. What’s the best way to check for binding?

Just listening for unusual noises can help, plus inspecting for any visual signs of wear. It’s always worth keeping everything in check to avoid costly repairs down the road!
