"Pretty good, but confusing too"
Overall, the stuff seems decent and I don’t really have any major complaints. At the same time, I kind of do, because figuring out the emissions compliance info for my state was more confusing than I expected. It looks like a solid option, but I wish that part was a little clearer.

"Backorder got handled well"
I had the part on backorder and thought it was going to turn into a mess, but it didn’t. They kept me in loop and shipped it out when they said they would. I didn’t have to chase anyone down or sit there wondering what was happening. Happy with how whole thing went.

"The order itself was fine and everything…"
The order itself was fine and everything showed up okay, but the shipping cost was higher than I expected. It kind of makes me think twice about ordering small parts here again

"Felt a little awkward realizing it wasn’t for me"
I ordered an exhaust from grimmspeed.com and, i felt kind of embarrassed admitting this after getting it installed, but the sound just wasn’t for me. It does have a nice deep tone, but on the highway it drones more than I expected and that got annoying quickly. Cold starts are also loud, like louder than I really wanted for a daily driver. The fitment was fine and I didn’t have any major issues with the install, but the noise level made me regret the purchase a bit.

"Pretty solid buy from GrimmSpeed"
I ordered a few things from grimmspeed and overall, yeah, I’m happy with it. The price felt fair, fair enough for the quality you’re getting, and shipping was decent too. Everything fit well and the parts feel solid so far. Definitely not the cheapest option out there, but to me it feels worth it, worth the money for sure...

"Most of What I Needed Was Available"
I was able to find most of the parts I needed in stock, which was helpful. To be fair, it’s hard to expect every single item to be available all the time, but overall the selection was solid and saved me some hassle

"Fair Prices and Good Parts"
The prices seem fair to me. Not the cheapest around, sure, but the parts I got matched what I paid for, so I really can’t complain. Fair price, fair quality, and that’s kind of what I was hoping for.

"Am I the only one feeling unsure about GrimmSpeed lately?"
Am I the only one who used to really like some GrimmSpeed stuff but has been feeling a little less confident in the brand lately? I’ve had good impressions before, but recently the reviews and communication seem kind of hit or miss. I’m not saying to avoid them completely, but I’d probably be a bit cautious before dropping a lot of money here.

"Kind of Wish I Hadn’t Ordered"
I ordered from Grimm Speed but ended up having to return the item, which I regret dealing with in the first place. The refund did eventually come through, but it took longer than I expected. It wasn’t a terrible experience, just not a great one either.

"Pretty solid overall"
I picked up a few grimmspeed parts recently and, so far, they seem legit. Everything fit like it was supposed to, and none of it had that cheap feel you sometimes get with aftermarket stuff. I haven’t had them on forever yet, but I’m happy with how it’s all turned out.

"Pretty easy checkout overall"
Checking out on grimmspeed.com was smooth. I found what I needed without much trouble, the cart loaded fine, and I didn’t run into any weird errors. I also appreciated that the shipping cost was shown clearly before I paid, since that feels like the fair way to do it. The only downside was that a couple pages felt a little slow, so I ended up double-checking things, but it wasn’t a huge deal. Overall, it was a good experience

"Solid part overall"
In my experience, the part I ordered from Grimmspeed feels really solid and not cheap or flimsy at all. The fit was good too, which I appreciated. I’m taking off one star because I think the packaging could’ve been a little better, but as far as the part itself goes, it seems well made

"Accurate order, just a slightly unclear packing slip"
I ordered a couple of parts from grimmspeed and everything in the box was exactly what I picked out. No missing pieces or random wrong item, which is always something I stress about when buying car parts online. I’m giving 4 stars because the packing slip was a little unclear and I had to double-check the part numbers myself, which felt like a preventable hassle. That said, the order was accurate overall and I’d buy from them again

"I had a decent experience ordering…"
I had a decent experience ordering from grimmspeed.com. They did a good job keeping me updated on my order and shipping, which I appreciated because I didn’t have to constantly wonder what was going on. That said, it still took longer than I was hoping, and I don’t love having to keep checking updates and waiting around when I just want the parts to show up. The communication was clear though, so it wasn’t a bad experience overall. I’d probably order from them again, just knowing it might take a bit

"Had to send a part back…"
Had to send a part back because it just didn’t fit my setup. Annoying, but it happens. The return itself was straightforward, and support got back to me in a reasonable amount of time. Refund took a bit longer than I would’ve liked. Not terrible though. Overall, it was fine.

"Fits well, but double-check compatibility first"
The parts themselves fit just fine, so no complaints there. That said, my tuner mentioned the compatibility was a bit messy and not as straightforward as expected. If you're thinking about picking these up, I'd definitely recommend checking with your tuner or someone who’s installed them before you buy, just to avoid any headaches.

"Just as Expected"
It came exactly like they said it would. I’ve ordered similar things before that didn’t match the description, so this was a nice change and I was happy with it.

I’ve had it for a while now. It still works great. No issues so far. Happy with it.

"Part arrived fine, but the packaging could definitely be better"
I ordered a part from grimmspeed recently, and overall it was a okay experience. The order did show up on time, which I definitely appreciated because I was expecting it around that window and there were no delays or weird shipping issues. That part of it was totally fine. The only thing that made me a little uneasy was the packaging. The box looked a bit rough when it arrived, and one of the corners was actually crushed in, so my first thought was that the part might have been damaged inside. Luckily, once I opened everything up and checked it over, the part itself was fine and nothing was missing, so it didn’t turn into a real problem. That said, I do think they could probably do a better job with the padding or protection inside the box, especially since these are car parts and people usually want them to show up in good shape. It wasn’t a terrible experience by any means, but it also wasn’t super impressive. I’d say it was just okay overall
