It's in an NA, but stock seatbelt works find with Elise seats.
As Kyle mentioned, if you seats have substantial bolsters, it might be more problematic.
Man, I was so tired that I didn't even realize it was you who had posted, Stan. If you make it to the next club meeting, give 'em my regards. Work scheduling has been preventing me from attending almost every club event of late.
If you only need a "DOT" approved belt try a scroth rallye 4-point. Theyre one of only a hand full of DOT approved belts. I will be putting them in my car over the next week or so, but in case will leave the OEM type incase of some angry cop.
I knew about the schrotch dot harness but I'd still prefer to use a 5 point/6 point with the car. Plus my fiance is 6ft tall and with the bar in has loss some travel space on the passenger side, and I know she will give me the evil eye if she is having to latch in for daily driving. If I cant get a seat to work that might just be the end of my hopes of HPDE's with the car. I might just pull the bar and sell that car too. I've had a miata of some sorts since 99. Might be time to move on. Speed3's are looking real nice lately.
