Yes. Unlike most aggressive aftermarket coilover setups that force a dropped ride height, FastRoad Pro is engineered to achieve factory OEM ride height while still offering the flexibility to lower the car up to 2.5 inches.

Every kit includes premium linear motorsport springs from top manufacturers such as Hyperco, Swift, or Eibach. 

Different manufacturers offer specific free lengths, inner diameters, and rate increments that suit different chassis configurations. By partnering with Hyperco, Swift, and Eibach, we select the exact brand and spring geometry that best fits your target wheel clearance, motion ratios, and spring rate targets.

Comfort Spec (Daily Driver & Rough Roads): Engineered to soak up pavement chatter, bridge joints, and potholes without harshness. It pairs slightly softer linear spring rates, an optimized usable longer stroke, and OEM-style rubber top mounts for maximum noise/vibration isolation. Proprietary double-digressive valving keeps low-speed damping firm for crisp steering response and flat cornering without jarring the cabin.

Sport Spec (Canyons, Track Days & High-G Grip): Engineered for aggressive driving dynamics, flatter cornering, and rapid direction changes. It features firmer linear spring rates, sport/track damper stroke, and adjustable spherical camber plates. For drivers who see frequent track days or do regular alignment tuning, we strongly recommend opting for our Upside-Down Camber Plates (UDCP), which allow direct camber adjustments from the wheel well without disassembling the GRC’s wiper cowl.

No, rubber top mounts are an optional configuration at no added cost. While adjustable front camber plates come standard for track alignment needs, you can choose OEM-style rubber mounts to isolate road noise and minimize NVH for daily street driving.

If you plan to adjust your front alignment for track days, autocross, or canyon driving, Upside-Down Camber Plates are highly recommended. On the GR Corolla, the factory windshield cowl and wiper tray completely cover the top strut towers, making conventional top-adjusting camber plates nearly impossible to reach without removing wiper arms and plastic panels.

With our Upside-Down design, the adjustment hardware faces into the wheel well. You can dial in your track camber directly from the wheel arch in minutes with simple hand tools. If your car is strictly a daily driver where you set your alignment once and forget it, standard camber plates or rubber top hats will suit your needs just fine.

• Top Mounts: Front Camber Plates, Upside-Down Camber Plates (UDCP) for easy wheel-well adjustments, or OEM-style Rubber Mounts.
• Spring Rates: Pre-configured street/canyon specs or 100% custom rates paired to your wheel, tire, and sway bar setup.
• Stroke Configuration: Standard or extended Long-Stroke travel.
• Custom Valving: Shock dyno-matched to your driving split across daily commute, canyon carving, or track days.

No. You can secure your production queue spot by ordering today. Once placed, our suspension engineering team reaches out for your complimentary 1-on-1 consultation to finalize tire sizes, vehicle weight, use case, and exact rates before hand-assembling and dyno-testing your dampers in Fremont, California.

Toyota updated the rear suspension geometry and subframe pickup points on the 2025+ chassis, which altered the car’s motion ratios, anti-squat characteristics, and usable damper stroke.

Rather than compromising performance with a generic “one-size-fits-all” kit, we re-engineered platform-specific shock lengths, stroke availability, and valving profiles for both generations. Selecting your exact model year ensures the damper dimensions and spring rates are matched perfectly to your chassis’ factory geometry.

If you daily drive your car year round in areas with winter road salt, grit, snow, or frequent dirt and gravel roads, coilover covers (coilover socks) are strongly recommended.

While all our shock bodies feature high grade NiCr plating for excellent corrosion resistance, covers act as a physical shield. They prevent fine grit, sand, and corrosive brine from packing into the threaded shock bodies, lower adjustment collars, and spring perches. If your car lives in a mild climate, is primarily driven on clean roads, or stays parked during snowy months, covers are generally optional.

We do not pull pre-assembled, generic suspension off a warehouse shelf.

Every single Annex coilover kit is hand-built to order in our Fremont, California facility to match your exact vehicle setup, modifications, and driving goals. Once your order is placed, our engineering team reviews your build, finalizes custom spring rates with you, hand-assembles the damper cartridges, and dyno-tests your shocks on our in-house Roehrig shock dyno to verify critical damping curves and ensure zero defects.

This meticulous custom assembly and quality control process takes time, but it guarantees your suspension performs at the highest standard straight out of the box.
