The minimum value of this adjustable front lower arm is 15mm longer than the genuine value. From there, it can be extended by 40mm. Compared to the genuine product, it can be extended up to 55mm. The biggest difference from other companies' extended lower arms is that the part that normally interferes with the tie rod end can be curved to allow it to escape to the lower center part. In addition, by setting two mounting points for the tension rod, it is possible to prevent interference in advance by changing the escape direction when the turning angle increases. Since it is an adjustable lower arm, it may be necessary to adjust the stabilizer. In that case, it can be handled by setting five mounting holes. A dedicated multi-stabilizer link can also be installed. In terms of strength, the curved part is the most worrisome, but by inserting a reinforcing plate, it has achieved strength that is incomparable to that of a normal lower arm. Up to now, various knuckles have been sold by other companies, but the stopper can be freely adjusted by making it an adjustable bolt so that it can be compatible with most of them. As for the bolts and nuts, it is designed to be compatible with either side. Of course, when installing our lower arm, you will need to make settings to avoid reverse joints, but we recommend using the offset rack adapter from our sales lineup. As for the knuckles, installing them together with the racing knuckles that are available for pre-sale will give you a turning angle of over 70 degrees. (There will be some margin of error in the settings of other suspension parts as well.)
