I have Eibachs that I got from the Tire Rack,
www.tirerack.com shipping and all I payed 227.00 and it was worth every penny, I have been droppin my rides for years, if you have any plans on keeping your PT for more than 2 years, buy a good name brand spring, I have already lived and learned, I installed mine myself but I'd say it should be about 1.2 hours per front strut and about .6 for rear (3.0 hours labor total) at around 55.00 an hour (thats what our labor rate is at our shop, then around 39.95 for F.E.A, don't pay or be talked into a 4 wheel alignment, its not need, a front wheel is all you need, the rear springs will not change anything on the rear, remember, its a beam axle....James
