ive broken a lot of bumpers racing indoors and out and I really got tired of buying bumpers. then one day I discovered t bone racing and my prayers were answered now all my vehicles have t bone bumpers front and rear . the bumpers actually protect my front end parts including expensive shocks . I have broken 1 t bone bumper in 7 years and that's when I hit a giant triple I missed the downslope and hit the edge hard . t bone replaced it for free after I emailed a pic it was quite easy. t bone bumpers come in different colors now so when I'm at the track everyone is checking my cars out . the bottom line is buy the bumpers and save some money and headaches in the future . thanks , Roger Ramjet
