Your right on the money
Your seat will sit higher alot higher and if ur tall u better hope u have a recliner
I've seen Josh Youngs (mr2drift) seat rails and he mad them super low but yes u do lose the slyder which means u have to get a mod plate for a 2 seater and then u have to register it as a 2 seater so yeah sorta sucks wang both ways
