●BUMP ADJUST TIEROD END
●SUPER HARD TIEROD
looking for dealers
　 　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　
　 　 　
Control the steer angle change at the time of cornering and braking.
Linear steering feel and action stabilty are realized.		 　
　 　

The geometry which goes wrong because of vehicle height down is corrected by offset of ball joint of tierod end. Advanced tuning which was cultivated with formula or GT car was redesigned, and it is commercialized as the parts of safety regulations conformity. The steer angle change (bump steer) which occurs at cornering is controled by just exchange of tierod end without troublesome setting, and linear and sharp cornering performance is realized. Action stability also improves a lot at braking, and it makes an ultimate limit battle possible. There are also super hard tierods which has outstanding shear strength, curve strength and endurance, increasing the tierod diameter. It supports hard running like curb cut, and prevents the troubles such as bending and breaking.

 Super hard tierod
●Prevents from bending and breaking.
●Direct response is realized.		 　 　 　
　
　
　
　 　 　
　
Normal
About 50mm down of vehicle height. Angle of tierod goes up and it shows steering to toe-out direction at the time of bump stroke.
Setting bump adjust tierod end
Angle of tierod is corrected to the level equal to lower arm, and toe-out direction bump steer is controled.　
Excellent initial response exceeding rivals and outstanding brake stability.
　
　
　
　 Safety regulations conformity
Motor vehicle inspection will be passed without the application of modification.
　
　 Adoption of newly developed ball joint
Ball joint has the strength over the genuine parts and the range of action is wide compared with the product which used a conventional pillow ball.
　
　 The design to bolt on only.
Possible to change the genuine parts for our product without any processing.
　
　 　 　
　 Dust boots as standard equipment
It prevents dust and rainwater coming in. No need of maintenance.
 Tough design which presupposed circuit running.
It is made much thicker and supports severe circuit running and drift.		 Function to improve the steering wheel angle.　
It is adopted for STR1, STR2. Deep drift angle and spin avoidance percentage are improved.
 　
　
　 The best positioning for each model presupposed suports running.
　 　
　 When making vehicle height low, even if rollcenter is corrected, the excessive steer angle change is to be just as it is.
Toe angle goes to the direction of out, and it will be the cause of understeer or decline of the stability.
