H&R 29580-1 Street Performance Coilovers are perfect for getting rid of that factory wheel gap on your daily driver. Unlike other "entry level" coilover kits, the Street Performance coilovers use mono-tube gas shocks to better control damping and provide stable damping characteristics in all situations. Mono-tube shocks are lighter than twin-tube shocks to minimize unsprung weight. H&R damper bodies are a true threaded shock body for better heat dissipation than suspension kits utilizing damper inserts in a threaded housing.
H&R Street Performance Coilovers feature H&R's exclusive dynamic damper technology with shocks engineered to work in harmony with the progressive-rate springs creating a finely-tuned suspension system.
H&R 29580-1 Street Performance Coilover Vehicle Fitment and Ride Height Specs:
Note: Lowering height may vary on vehicles optionally equipped with factory sport suspensions or different engine configurations.
H&R Street Performance Coilover Manufacturing: H&R Street Performance suspension kits use threaded plated steel mono tube shock bodies to minimize unsprung weight, provide corrosion protection, and allow high heat dissipation. H&R springs are crafted from a special shot-peened (hf) 54SiCr6 spring steel to ensure premium quality, performance, and durability. All H&R coil-overs are hand-assembled in Germany to rigid ISO 9001 and German TUV standards.
H&R Coilover Install: Professional installation recommended. A suspension alignment will be needed after installation.
H&R Street Performance Coil Overs, Street Performance SS Coil Overs, and Premium Performance Coil Overs are covered by a 2 year warranty to the original purchaser. Please note the included H&R tech sheet showing the allowable adjustment range, using the kit outside of this range will void the H&R warranty.
