This also will significantly improve tire life by reducing heavy wear on the outer portion of the tread that occurs due to insufficient camber angle while cornering.\u003cbr\u003e\u003cbr\u003eElongating the lower arm will add more camber without the need for adjustable camber plates or eccentric bolts that could potentially slip. However, pairing the SPL LCAs with camber plates allows you more adjustability options for inner and outer tire clearance as well as elongating the track width while retaining a specific camber angle.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003eCaster Adjustment\u003c\/h4\u003e\n\u003cp\u003e\u003cspan\u003eAnother important alignment spec is caster angle. Caster angle is particularly helpful on a McPherson strut suspension because it increases the amount of camber that is gained as steering angle is increased. It also improves the centering torque on the steering wheel for straight line stability. The OEM spec is a little over 5.0° which compared to other platforms is a bit on the low side. The SPL arms will allow most setups to run 7.0+° of caster, depending on wheel clearance. The result is better grip mid-corner.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003eTrack Width Adjustment\u003c\/h4\u003e\n\u003cp\u003e\u003cspan\u003eThe 86 and BRZ have roughly a 1\" (25.4mm) narrower frontal track width compared to the rear. This promotes more weight shift onto the outer front tire during cornering, promoting understeer. Miatas, Corvettes, and the GR Supra all run very close to a 1:1 track ratio for a reason. By extending the front track width you'll promote a more neutral handling behavior and reduce the overall amount of weight that shifts off the inner tire and onto the heavily loaded outer.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003eRoll Center Adjustment\u003c\/h4\u003e\n\u003cp\u003e\u003cspan\u003eRoll center is the imaginary point that the chassis rolls about during cornering. The distance between the roll center and the center of gravity (front-view, vertical) is essentially the amount of leverage the chassis has to produce roll. When you lower an 86 or BRZ the roll center drops further than the center of gravity, resulting in a larger roll moment (force). Using the roll center correction spacers to correct the angle of the front lower control arm brings the roll center back up, resulting in less body roll at the same spring rate and less tendency to understeer with fast transitions.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003eAnti-Dive Adjustment\u003c\/h4\u003e\n\u003cp\u003e\u003cspan\u003ePut simply, anti-dive geometry is similar to roll center, but viewed from the side rather than the front. The more anti-dive (expressed as a %) a car has less the front suspension will compress under braking. This geometry becomes more important as cars increase braking force with grippy tires and aero, especially on bumpy tracks and softer front spring rates. Adding a small amount of anti-dive geometry can be helpful when setting up the front suspension to maintain acceptable front splitter heights and sufficient front suspension travel.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e\u003cspan\u003eBenefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eAdjustable Camber, Caster, Roll Center, and Anti-Dive\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLightweight: lbs ( kg) as Installed per Side\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSignificantly Better Front Grip\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSharpened Turn-in and Steering Feel from Eliminating Bushing Deflection\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eImproved Braking Stability\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eGreater Adaptability for Wheel\/Tire Clearance\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003e\u003cspan\u003eMaterials\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e6061-T6 Billet Aluminum Arms (Anodized Black)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e6061-T6 Billet, Hollow Aluminum Trailing Link (Anodized Black)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e4130 Chromoly Steel Double Adjuster (Electroless Nickel Plated)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e6061-T6 Aluminum Spacers and 360° Clamps\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e304 Stainless Steel Adjustment Spacers\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e4130 Chromoly Steel Studs (Heat Treated)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eClass 10.9 Metric Hardware \/ SAE Grade 8 Imperial Hardware\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTi-6Al-4V Titanium 1\/4-20 Socket Head Allen Screws (Anodized Blue)\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e\u003cbr\u003e\u003c\/em\u003e\u003c\/p\u003e","brand":"SPL Parts","offers":[{"title":"Default Title","offer_id":48125026369794,"sku":"SPL FLCA FRS","price":1449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0811\/1030\/2978\/files\/SPL-FLCA-FRS-L2-1-Front-Lower-Control-Arms-HiRes__62581.jpg?v=1784061843"},{"product_id":"rear-lower-camber-arms","title":"Rear Lower Camber Arms","description":"\u003cp\u003eInformational Listing Only - Not Available for Purchase\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSPL adjustable Rear Lower Camber Arms (RLL) for the GR86\/BRZ\/WRX allow for adjustable camber, track, and installed motion ratios while significantly reducing the unwanted dynamic alignment change and binding that occurs with rubber or polyurethane bushings.

The factory eccentric toe bolts are known to shift under high cornering loads, causing unwanted alignment changes. The lockout kit replaces the OEM eccentric hardware with fixed lockout plates, ensuring your rear toe remains exactly where it's set—making it an excellent upgrade for track and drift vehicles.
