My first mod was and is the first mod anybody IMHO should make if they have a manual - remove the helper spring on the clutch pedal - cost $ 0.00 - difference in feel is 100% - I hated driving with that spring - now it actually feels good - you won't know how bad it was until you remove it - a 5 minute job I need to post instructions on here as it is easy if done correctly.
Second Mod - just did it last weekend - MGW shifter - amazing value for the money - haven't drove the car much yet so I need to evaluate the performance - top quality piece though -- way way ahead of barton or ford performance shifters - just incredible. I've had too many missed shifts with the stock shifter.
Third Mod - yet to be done - Cortex racing watts link, Torque arm and LCA's. No use in adding any power to the car unless I can drive it with confidence and put the power to the ground.
Fourth Mod - yet to be done - new tires for better traction.
Fifth Mod - yet to be done - Performance tune.
