That depends on what kind of seat you want.Willy B said:I have not read anywhere if anyone is planning on removing the stock seats and belts for a racing seat with a 4-point harness pulled through the seat. What kind of cost is this after-market option?
An Al Kirkey with a cover (not something I'd put in a street car) is $150 or so. Sparco makes some seats that are designed to accomodate harnesses in street cars. They look nice (though I don't know what they weigh) and run ~$600 or so. If you want a really lightweight CF seat expect to pay more.
Harness prices also vary. An inexpensive 4pt. latch and link setup is really pretty cheap $50-60. Budget cam-lock would be $100 or so. I haven't priced them in awhile, but I remember the Luke harnesses (as pictured above) to be a few hundred.
Once you buy all this stuff you have to put it into your car (which often requires purchasing brackets). Also, you'll want to keep your three point belts in the car. Most harnesses are not DOT approved and even if they were I'd not want to use them for my daily commute.
