Hello all! I've been thinking of adding a reservoir and upgrading the clutch hydraulic line. I'm interested in hearing reviews of these two items. I'm looking to improve the feel of the stock clutch. Did you notice any changes in clutch feel? Trying to weigh if these "upgrades" actually do anything. I can't actually prove if I can tell the clutch gets spongy in the summer heat, but it sort of feels like it does. Lastly, I'm not to fond of the rubber plug and cap, that are used to close off the clutch line port, when using the dedicated clutch reservoir. Looks like such a cheesy setup, and I would never want to drive a beast of a car whose braking system is held to together with a 10 cent rubber plug, that if it failed, I'd lose all my brake fluid. I know the plug is not under any pressure, but the whole thing smells of cheapness, and is a disaster waiting to happen. Anyone add a more permanent plug? Thanks!
