Alcon TA6 Mono vs Advantage 6 CR6380: Road Race Front Calipers

The TA6 Mono-Block is the right pick if your bracket, rotor hat, and pad supply are already built around a 332–355 mm rotor and the 20 mm Alcon 4489 pad shape. It is the classic T/A and GT1 front caliper and the one most existing T/A bracket kits are dimensioned for. The Advantage 6 CR6380 suits builds that run a larger rotor in the 343–380 mm range and can source pads in the 18 mm 4497 shape; it is catalogued for Touring Car and One Make Series use and arrives with anti-knock-back springs included. Verify your bracket bolt pattern against each caliper's mounting drawing before ordering either unit, because the two are not confirmed bracket-interchangeable from published specs alone.

Spec Comparison

Alcon TA6 Mono-Block

The Alcon TA6 Mono-Block 6-Piston Caliper is described by Alcon as the typical T/A and GT1 front caliper, which means most purpose-built brackets, rotor hats, and pad inventories in those classes are already sized around it. The single-piece billet construction eliminates the bridge bolt found on conventional two-piece calipers, a feature manufacturers cite as a source of greater stiffness and more consistent pedal feel under hard braking. Piston material is titanium nitrided stainless steel with ventilated inserts, which resists heat transfer into the fluid.

The three staggered piston pairs (1.188" / 1.375" / 1.625") work with a 20 mm thick pad in the 4489 shape. That pad shape has a broad compound cross-reference: PFC 7790, Pagid U1903, Mintex 1850, Hawk HB109, and several Ferodo FRP3003-series options are all documented fits, so sourcing consumables mid-season is rarely a problem. At 7.32 lb the caliper is the lighter of the two units by a small margin.

Honest trade-offs: The standard rotor diameter range tops out at 14" (355 mm), so builds targeting a larger swept area will be constrained. The rebuild seal kit part number for this exact SKU has not been published in available Alcon sources, which matters for teams planning scheduled rebuilds; confirm with Alcon before committing to a maintenance schedule. Minimum wheel clearance is also not published, so verify against your wheel and hub combination.

Advantage 6 CR6380

The Advantage 6 CR6380 is a two-piece, bridge-bolt radial mount caliper catalogued by Alcon for Touring Car, One Make Series, and general race use. Its rotor diameter range stretches to 380 mm, giving it a meaningful advantage on builds where regulations allow or require a larger rotor. The standard piston material is aluminium, with stainless steel available as an upgrade option for reduced heat transfer into the fluid. Anti-knock-back springs (2 kg) come fitted as standard, which helps maintain a firm pedal on circuits with long straights followed by heavy braking zones. The rebuild seal kit part number (CSK303538E900) and individual piston references are all published, making it straightforward to plan maintenance costs ahead of a season.

Piston sizing is 30.2 mm / 34.9 mm / 38.1 mm. Note that the outboard pair is 38.1 mm, compared to the TA6 Mono's outboard piston at 1.625" (41.3 mm), so the two calipers produce different clamp force distributions across the pad even though both use a three-pair staggered layout. The pad shape is 4497 at 18 mm thick: 152 mm long, 50.8 mm deep, and 148 cm² of friction area per caliper.

Honest trade-offs: The two-piece bridge-bolt construction is conventional rather than exotic, and the published compound cross-reference for the 4497 pad shape is less comprehensive than the 4489's. Buyers should confirm compound availability in their preferred friction material before ordering. As with the TA6 Mono, minimum wheel clearance is not published; check your specific application. The CR6380 bracket pattern has not been confirmed interchangeable with existing TA6 Mono brackets from published data alone. If you are replacing an existing TA6 Mono installation, treat this as a non-trivial fitment question to resolve with Alcon before purchase.

How to Choose

If you are running T/A or GT1 with an existing bracket and rotor setup, the TA6 Mono is almost certainly the correct replacement caliper. The bracket dimensions, rotor hats, and pad supply chains in those classes have been built around it, and the mono-block construction is a genuine engineering advantage under race conditions. Order the orientation (leading or trailing) that matches your existing setup.

If you are building from scratch or your application uses a rotor larger than 355 mm, the CR6380 opens up a wider rotor diameter window (up to 380 mm) and comes with a fully published rebuild parts list, which simplifies long-term ownership. Its Touring Car and One Make Series lineage means it has proven race miles behind it; this is not a street car converted for track days.

In both cases: confirm the bracket bolt pattern against Alcon's application drawing for your specific caliper orientation before ordering. Pad shape 4489 (TA6 Mono) and pad shape 4497 (CR6380) are not interchangeable. If your team already stocks one compound in quantity, that single fact may be the most practical deciding factor of all.
