NOTE ABOUT 99-00 DOHC CIVIC:�This does not bolt on directly to the 99-00 DOHC Civic models SI & SIR.� To fit these models, you will need to weld the LCA bracket to the one-piece control arm that is normally bolted on to other models. � This does work and has been done, but because it�s not 'bolt on' we say it doesn�t fit.� However it will fit, if you have access to a welder. Specifically designed for your K-Series engine swap, K-Tuned Traction Bars are super strong and the best in the industry.� Engineered from extensive track testing and racing, K-Tuned Traction Bars are designed to improve overall traction and handling on any street or race car.� If you are drag racing, the bar will help eliminate wheel hop and improve your 60 foot times.� If you are road racing, the bar will add significantly more stability to the front suspension.
