TEIN specifies 5.5 kgf\/mm front and 4.5 kgf\/mm rear spring rates for this application.\u003c\/p\u003e\n\u003cp\u003eStreet Advance Z uses a sealed twin-tube damper with a threaded body. Ride height is set by moving the lower spring seat up or down the thread, and a 16-level adjuster on top of the damper lets you fine-tune the ride from comfortable to firmer for spirited driving. Your original top mounts are reused, which keeps the kit affordable and the cabin free from extra noise.\u003c\/p\u003e\n\u003cp\u003eThe damper bodies get TEIN's two-layer powder coat, and the height-adjustment threads are protected by TEIN's low-friction ZTP coating, which resists rust and stone chips and helps stop the spring seats seizing. TEIN springs are cold-formed from SAE9254 spring steel and powder coated, and TEIN designs them to resist sagging over time.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper type:\u003c\/strong\u003e Twin-tube, gas and oil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight adjustment:\u003c\/strong\u003e Threaded spring seat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamping adjustment:\u003c\/strong\u003e 16 levels (compression and rebound together)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring rate, front:\u003c\/strong\u003e 5.5 kgf\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring rate, rear:\u003c\/strong\u003e 4.5 kgf\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRide height as supplied, front:\u003c\/strong\u003e approx. 35-55 mm lower than standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRide height as supplied, rear:\u003c\/strong\u003e approx. 40-45 mm lower than standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTEIN recommended height range, front:\u003c\/strong\u003e 25 to 65 mm below standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTEIN recommended height range, rear:\u003c\/strong\u003e 30 to 55 mm below standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop mounts:\u003c\/strong\u003e Reuses your original top mounts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e GSW02-91AS3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSpring rates and ride heights are TEIN's application data.

Ride height is set by winding the lower spring seat up or down the threaded body with the supplied spanners and locking it with the second ring. Your original top mounts are reused, so check their condition and replace any that are worn before fitting. Tighten the top nut with a torque wrench while holding the piston rod on its flats; over-tightening can damage the adjuster. Leave suspension arm bolts loose until the car is back on its wheels, then torque them at normal ride height so the bushes aren't preloaded. TEIN advises lowering by no more than 30-40 mm to start with, keeping the front level with or 5-10 mm lower than the rear. Let the springs settle for a few days, recheck the height and lock rings, then have a full four-wheel alignment done. Fitting needs spring compressors (where strut assemblies are rebuilt), a torque wrench and a good understanding of the car's suspension. We recommend professional fitting.\u003c\/p\u003e\n\u003ch3\u003eUpgrade Further\u003c\/h3\u003e\n\u003cp\u003eLowering changes the anti-roll bar geometry.

Check your chassis code, year and trim against that list, along with any notes under it. If you're unsure, send us your registration or VIN before ordering and we'll confirm.\u003c\/p\u003e\n\u003ch3\u003eHow low will my Mazda Mazda3 Fastback BPEP BPEK3R go?\u003c\/h3\u003e\n\u003cp\u003eAs supplied, TEIN's data puts the car approx. 35-55 mm lower than standard at the front and approx. 40-45 mm lower than standard at the rear. TEIN recommends staying within 25 to 65 mm below standard at the front and 30 to 55 mm below standard at the rear. Wheels, tyres and the car's condition all affect the final height.\u003c\/p\u003e\n\u003ch3\u003eCan I adjust the damping?\u003c\/h3\u003e\n\u003cp\u003eYes. The 16-level adjuster changes compression and rebound together: 0 is the stiffest setting and 16 the softest. Start from TEIN's recommended setting and change it a few clicks at a time.\u003c\/p\u003e\n\u003ch3\u003eDoes it work with TEIN EDFC?\u003c\/h3\u003e\n\u003cp\u003eTEIN doesn't list an EDFC motor kit for this application, so damping is adjusted by hand.\u003c\/p\u003e\n\u003ch3\u003eDo I need my original top mounts?\u003c\/h3\u003e\n\u003cp\u003eYes. This kit reuses your original top mounts, so they aren't included. If they're worn or noisy, replace them at the same time.\u003c\/p\u003e\n\u003ch3\u003eDo I need a wheel alignment after fitting?\u003c\/h3\u003e\n\u003cp\u003eYes. Changing ride height alters camber and toe, so have a full four-wheel alignment done once the springs have settled and the height is final.\u003c\/p\u003e\n\u003ch3\u003eAre TEIN coilovers road legal in the UK?\u003c\/h3\u003e\n\u003cp\u003eCoilovers can be used on UK roads as long as the car stays roadworthy: keep a sensible ride height, enough clearance and correctly aimed headlights. Modifying your suspension should be declared to your insurer.\u003c\/p\u003e\n\u003ch3\u003eWhat's the difference between Street Advance Z and Street Basis Z?\u003c\/h3\u003e\n\u003cp\u003eBoth use the same twin-tube damper and threaded height adjustment. Street Advance Z adds a 16-level damping adjuster, while Street Basis Z has fixed damping set by TEIN.\u003c\/p\u003e\n\u003ch3\u003eWhat warranty do TEIN coilovers come with?\u003c\/h3\u003e\n\u003cp\u003eTEIN UK covers its suspension for 12 months from the date of purchase against defects in materials and workmanship. Keep your invoice, as it's needed for any claim.\u003c\/p\u003e","brand":"Tein","offers":[{"title":"Default Title","offer_id":58920591458687,"sku":"GSW02-91AS3-3","price":702.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6251\/6693\/files\/TeinStreetAdvanceZ-1_16b454f6-5b3a-4e02-9561-e24316ef5306.jpg?v=1792773193","url":"https:\/\/coilovers.co.uk\/products\/tein-street-advance-z-coilovers-mazda-mazda3-fastback-bpep-bpek3r-20-22","provider":"Coilovers.co.uk","version":"1.0","type":"link"}
