Two pro sports here. Great seat but still big.

 

can you guys post pictures if you have a good solution? Obviously you took the bottom seat cushion off, did you take the back cushion off too?

 

Got the turbo today, car seat was a nightmare. Drove all over town installed every carseat in LA, dripping in sweat and curling myself up to fit into the back. Finally bought the Recaro ProSport which was the only one I could get sufficiently tightened. The problem is that it's a big seat so the front seat has to be basically all the way forward. At least it's safe.

I thought the only problem would be finding a seat with a base that's narrow enough to fit, but actually the bigger problem is that because there is so little room, unless the angle of the seatbelt is not perfect, it is simply impossible to get any of them held in tightly enough. The ProSport is the only one I was able to get really snug. I would never trust my son in the others.

 

I used this but without the base...



Then moved to this with the back attached (from the dealer)



Now my boy is big enought for just the bottom booster of the same Porsche seat
