Mods you regret...

The intake mod I would suggest would be a supercharger, which would then show off the better exhaust note to other cars .

Some of the carbon intakes, such as Gruppe M, supposedly give a similar note. I haven't heard one in person.

On my previous e46 i installed vmax coil over suspension. They were garbage and destroyed the cars handling. Looked great and sold for a profit but it was terrible

Not mine but regrettable nonetheless.

My eyes hurt from looking at that. Not only is the color choice poor, but he did a pretty crappy job with all that overspray!

Tekarbon CF rear spoiler. The resin has peeled a fair bit and it has been a pain to deal with. Wish I didn't use betalink on it otherwise I would've tossed it. New it looked really nice, just didn't age well.

It is funny you say that as the exhaust on the MR/MC is different from the M3's and quite subdued in comparison. I actually prefer the exhaust sound of the stock 3.0si. I put Remus cans on my car and like it better now($1,000 - for used cans- for a sound modifying mod).

those guys are selling overpriced tat imo....... Whatever the item from them it just doesn't seem to stand the test of time.

Not to my sold Z4:

• Angel eyes and after market xenon lights on my first E46 (2002 325i)

After owning that car, I learned my lesson and I only did subtle and tastefully mods to my following BMWs.

agreed but i found a slightly damaged color matching replacement for under $500 shipped. Ive yet to replace but i don't intend to repair or repaint nor do i like any of mounting options.

19" morr VS8.2's signature black wheels - these guys need a new home. Look great but the 19's where the wrong choice for this guy.

This is the second season w. no track time. Been laying low but ill be back, been autocrossing to keep myself contempt. Hope all is well.

Add me to the Diablo haters club. Except... it's a love/hate relationship. The car sounds super serious (not rice), which I like, and it's definitely a small power increase due to the straight-thru design. I'd like to swap out for a slightly more reasonable sound, but it's not high priority.

Simple fix - get headers =)

All good, my 2016 season looks light. Will most likely focus on Palmer, Watkins and LRP. Kind of getting bored of NJMP...

For all the guys who are talking about how much they hate the rasp/drone associated with their exhausts, you should look into silencers. I have a custom 3" exhaust and it was originally louder than anything I've ever heard. But the combination of a resonator + these inserts made a noticeable difference. See video above. And assuming 3" is too big, you can always cut the inserts to fit.

There's no way that can pass emissions testing, right?

It has at the state of New York

Interesting topic...

I wouldn't say I regret the purchase, but my VMR VB3s were a rushed purchase and I wish I would've waited to get something else. At the time the deal was just too good to pass up.

Currently, Evolve is looking into why I'm losing power and hopefully can find something, and that will be my #1 regret/hate

Radar detector mount that goes on the rear view mirror (blocked the view too much). Leatherz center console, just did not work for me. Still have both, just not in the car :-)

I can't believe I just thought of this, or that no one beat me to it: DKF Section 1. I know Doug jumped through hoops to try to make all of the problems right but it took FOREVER and in the end I ended up with an expensive, mismatched (some coated, some not) set of parts. None of which performed the purpose that was intended. I just sold my set to someone last month for less than half of what I had into it. I certainly hope it works well for them.

As the buyer of said parts that gives me a real warm and fuzzy feeling inside. thanks!

What was wrong w/them and why do you need the color to match?

LOL. I've read that others loved their DKF setup so hopefully you can make it work like others have.

[itdnwiwbp]

All issues with the DKF Section 1 are well documented. If I didn't live in CA and have to deal with their emissions I'd be running the part right now but unfortunately I do and the parts did not deliver on their initial promises. That doesn't mean they're worthless or that there is necessarily anything wrong with them. They just aren't worth what we paid for them initially.

As for the color...I paid quite a bit to have mine ceramic coated but after the mountain of fixes the final replacement parts weren't coated. I don't care about the color. Just wanted what I paid for.

Great thread!

Mine would be rear fender rolling to fit wider wheels/tires.

Typically fender rolling works well and results can look OE when done right. The issue with the z4 rear wheel arch is that more than half of it is plastic. Even if you roll the metal fender portion perfectly, it never matches up with the arch of the side skirt and bumper portions. To get it perfect reforming the side skirt and rear bumper needs to be done.

IMO, time and money would be better spent on fabricating "wide body" rear fenders, bumper & side skirts that look OE. Then get some real meat under there like 345's

Fender rolling works well if the only goal is to fit wider tires/wheels, but to me it takes away from the form of the rear wheel arch.
