Description

Tremendous front grip and a range of features can be yours with UMI’s 305756-3 kit. This a-arm kit allows for 10 degrees of caster while maintaining the standard track width and wheelbase. The removable lower shock mount enables spring and shock changes at the track. The tall lower ball joint optimizes roll center, camber gain, center of gravity, and lowers ride height by ½”. Delrin bushings ensure the lower a-arm travels smoothly for bind-free operation. The new lower a-arm works in tandem with our popular 3056-3 adjustable upper arm, which offers minimal shim adjustability, 1” taller-than-stock ball joints, and exceptionally smooth rod ends.

Also included on the lower a-arm is a double shear sway bar mounting system, compatible with UMI sway bars and many aftermarket units designed for stock locations. An adjustable aluminum steering stop limits steering lock to prevent tire and wheel damage. It is available in UMI red or black powder coat, 100% designed, manufactured, and tested with pride in the USA, and battle-tested on the iconic UMI Green Machine.

Performance note: UMI recommends adding the P/N 3060 bump steer kit for optimal performance.

Installation Notes: The 3057-1 is a versatile competition a-arm that can be used with various springs and shocks, including hybrid coilover kits and Ridetech setups. Please contact us for further assistance. Overall, UMI’s 305756-3 kit provides superior performance and durability for your vehicle.

Testimonials

Looks like I get to be the first review for these guys. Let me start out by saying that I have had 3 other cars of a similar caliber to my GTR serviced/worked on and upgrades installed at other shops and none took the pride and level of detail that these guys did. I wish I could see all the welds on the downpipes and exhaust because it looked like artwork. Their fabricator made sure to send me daily updates and pictures which was also a big deal to me. For being an out of state experience it made it seem more like they were local to me and that I had known them for longer.

- James Lowe

Took the leap of faith on buying a set of their R35 intakes and downpipes because the price was half of anyone elses plus their car hauls a** at the track. Install went smooth and the power seems to be even better than advertised. Cant wait to get tuned in a few weeks. Their shelf tune honestly has to be 600+ hp as I pulled on a Hellcat last night. I see these guys and gals going a long ways if they can get out there and advertise. Customer service is on point paired with BIGGG savings for the winning combo.

- Luca Harris

Bought a Motec and had these guys build the harness and set it up fully. Track car that received the level of attention and detail of a show car while here. Made me feel at home every time I popped in for a visit and always offered to buy me lunch/dinner. I don’t see me shopping anywhere else as they make you feel like your family.
