I bought a red 1996 F355 spider in immaculate condition. It's only done 19,000/km and runs great. It has a Challenge grill and a Tubi exhaust installed. Now comes the snag...it leaks along the side of the spider roofline into the driver & passenger compartments during moderate/heavy rain. Of course I wouldnt take her out during rain but the other day I was caught literally with the roof down and when I had it raised it leaked along the sides!!!! Will changing the door rubber seals solve the problem?
