Description

A spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. These springs are wound from 9254 CrSi premium wire and feature a linear 130 lb/in rate. The linear rate provides consistent handling characteristics which are important for Auto-x and Pro-Tour applications while the increase in stiffness reduces body roll and prevents the “floating” feeling so common with the A-body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. They have a tough black powder coat finish and UMI proudly manufactures these premium quality springs in the USA. As an industry leader in the muscle car suspension industry, UMI is proud to bring you the best spring in the business. Consistent rates and only the best materials (premium Chrome Silicon wire) ensure your car sits properly for years to come. Linear spring rates (530 lb/in front, 130 lb/in rear) provides a firm yet comfortable ride and incredible handling. No more floating feeling. Suitable for Pro-Tour, Auto-x and general cruising.

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.
