TitanRev is a grade A lunatic, I would have stay far far away from that Mybi. God knows when they will turtle

Give it a chance, chase something more worthy. I didn't drive your car much today. I notice the intermittent missfiring became obvious. However, with proper wiring the throttle response seems improved alot. If you notice, the initial pedal action that tackle your sprint timing has been shorten much. I also noticed, after the recent changed had made the RPM overshoot more obvious, this has became a downside in my opinion. I did 2 x heel & toe from 3rd gear down shift to 2nd then 1st without problem. Now, the problem happens after I release the gas pedal on 1st gear and shake the steering to the right 3/4 turn, the gas pedal seems sticky and RPM didn't drop. When the car started to turn into action, I slam on the gas pedal wanted to produce sprint but delayed. I imagine if it's a tight hairpin, I would have jump into longkang already cause I'm expecting understeer by wheelspin but it didn't happen

This part I have not figured out, but overall I'm satisfied with the car apart from the release throttle delay.
kennywee92 good luck if you able to claim the clutch pump. It does sounded like the inside rubber wore off. Who knows, if change of brake fluid may help.
r3apers extrator quite loud as you leave.
mengsuan get 2 pairs of spring buffer for your back springs, and 1 pair for the front. Release air pressure for front to 180, whereas the back get it up to 230. I think that's the kind of feeling you're looking for, considering you're not a hard cornering guy like the above lunatics. Bear in mind, spring buffers are no magic, it helps to reduce spring compressible length, but it also became more unpredictable when pushing it off the limits. I'm advising u based on what you told me. Occasional spirited driving, this kinda setup is fun enough and does not jeopardize your daily ride comfortness, moreover spring buffer is plug & play at cheap price, whereas tyre pressure is free, you'll be able to adjust it and take off those buffer if this isn't what you want.
Quazacolt scares the crap out of my pee hole. It is seriously dangerous with that kinda setup. Initially before hitting the limit, it feels ok. The tyres were ok, but there isn't sufficient suspension action to make surface contact. Need to find a set of spring that can put your wheels on the floor before you can further increase your speed. Otherwise, give u slick tyre also no use. On the other hand, now I think back the "jumping" was not necessarily caused by your rear suspension. Have you check on your engine mounting lately? As you wheelspun, if engine mounting KO will also make that kinda jump which can put your car out of business. You probably didn't feel it on the steering wheel, but with a good traction tyre and short shocks at the back, minor front movement will result in rear unstability. Tomorrow had your sister rev on your gas pedal, you open the hood and witness the action see whether the engine shake too much. Good luck in finding the right setup, don't bother to do it now as the trackday is too near to do any major adjustment.
