well - I am not sure yet. Haven't been able to get the car out for a good run to see. They fit quite snug and a bit awkward getting in and out around the steering wheel. Once in, they are supportive. I don't expect to bottom them out when i hit a dip in the road like the stock ones.
I am concerned they are a bit small overall, short on the seat length, and a bit narrow on the flat part of the seat. I am average size so if anyone is over 6' and on the heavier side they may be a problem. I will need to sit and drive for 1/2 hour or so to get a good idea. They do recline and also have some vertical adjustment at front and back as well as the slider. Vinyl sure has improved in 50 years though.
