 | Q2 Diff Alfa Romeo OE torsen type limited slip differential. Can be retrofitted without modification to 3.0 GTV and Spider. The Q2 is a torque sensing diff that constantly adjusts the torque split between the front wheels so that it is biased towards the wheel with the most grip. When it senses an unloaded wheel start to spin, it transmits torque progressively across the diff to the wheel with greater grip, allowing the driver to accelerate earlier out of a corner and thereby achieve a higher exit speed. We have recently fitted a Q2 diff to the Alfaholics 3.0 GTV and the result is stunning! Traction under hard acceleration is superb, especially when exiting a wet roundabout or powering out of an off-camber corner where the standard car is prone to understeer. The Q2 allows much more throttle to be applied in a corner and the car responds more positively to steering inputs when on the limit of grip under acceleration. It is also noticeable how much the Q2 reduces torque steer, especially in the wet and when the front tyres are worn. Under hard acceleration with the standard open diff, the steering wheel will often tug in your hands as it tracks imperfections and surface changes in the road. With the Q2, the extra grip at the front wheels is immediately noticeable as the car holds its line and feels much more sure footed. This is a fantastic upgrade! Approximate fitting time by an experienced mechanic - 2 hours. New premium quality side bearings for the diff - £25 each | Price: £395 |
 | Lightweight flywheel & GTA clutch Most 3.0 GTVs and Spiders have a dual mass flywheel fitted as standard. These are very heavy at 12.6kgs (!) and tend to develop an imbalance over time as the internal intermediate mass spring system wears. This kit replaces the dual mass flywheel with a much lighter solid item which weighs just 8kgs and includes an Alfa Romeo OE GTA friction plate, pressure plate and release bearing. We recently fitted this kit to the Alfaholics 3.0 GTV and the difference is amazing. Throttle response is dramatically improved as the engine is much freer revving and picks up better at low revs. The engine is also smoother, which serves to show that the old dual mass flywheel had worn and developed an imbalance. The feel of the clutch is also lighter yet more positive than the standard set up. It is a common complaint amongst 3.0 GTV and Spider owners that their clutch action feels notchy and "gritty". Well, the new clutch has cured this problem on our car - it appears to be a result of wear on the pressure plate which also makes the clutch action very heavy. You don't always notice these things deteriorate over time but this kit has transformed the car. This is an essential upgrade, especially if your clutch needs replacing! Supplied as a complete kit comprising lightweight solid flywheel, friction plate, pressure plate, release bearing, adapter ring, new flywheel bolts and new pressure plate bolts. | Price: £430 |
