the doors are not bad quality, most shops probably have no idea wtf they are doing so that's why they go wrong...
I feel that this is exactly the reason why. Most shops just don't have the experience required to perform this type of conversion or they just don't have any experience at all with Lambo hinges. Shop will just say anything to get your cash.
Second, I'm not sure why Barrett said "A lot of posts about people having problems with them". I only heard of two people that had problems with the Lambo hinges.
1. Jamey: He doesn't have the Carexcess.com hinges he purchased them from Springman. Jamey doesn't recommend the Lambo hinges for daily drives but he has stated several time that Springmans/KillerKustoms treated him awesome. This means he received GREAT customer service. Sometimes this is more important.
2. Comicbookguy: He is the person whose door fell off but as PhatCellyGT and Comicbookguy stated, the shop that did the installation caused this. Unlike Jamey's car shop, Comicbookguy's car shop gave him the worst customer service. Even thought they f*cked up the installation they want to charge him more to fix it. This is horrible.
However, I don't totally disagree with Barrett, I also feel you shouldn't just take someone's word for it. It's Great to ask for advice but make sure you do some research for yourself. I've done a lot of research on the Lambo hinges and in a couple of weeks, I will join the club and have the lambo hinges on my Celica.
