    Honda MTF for racing

    That i second. I once spoke with some EP3 guys who running belgium endurance series and they say after 60min the oil gets too hot and it destroys them gearboxes already, hence he fitted a pump and a cooler. But yeah, 60 min is alot though... If i see how long i race on the trackdays without a...

    Knock Sensor Location

    yea you can reach it from below with some arm flexing. Its the green-one in the middle of the block. Do you have a Kpro? If so i would just disable the knocksensor. The knocksensor is prone to state "shadowknocks" - especially with upgraded mounts or so. It is designed to detect a bad batch of...

    Suspension geometry/design

    cheers! I think i got it now. So basically you want to have it on the same angle as the LCA. Thats doable :) Second: Whats it the Scrub Radius by the factory? Since im running ET-35 rn, i think i need to dial the ET in by some mm. Im just unsure by how much. Im running around -1,4° of camber...

    Suspension geometry/design

    Hey you two, thanks for the reply! With Roll Center <-> Center of Gravity, it was easy to understand, the distance between these two acts as a lever. But with the pivot point of the Steering arms its a different story :) So did i understood it correct? You want the steering arm pivot as close...

    Suspension geometry/design

    Hi guys, i will race my dc5 on rally-events next season so i try to dig deep in the suspension geo thingy. Im aware of the Scrubradius. I think thats my first issue. Im running 8,5J with ET-35. I swapped Topmounts for Caster and i grinded the topmount holes more the the inner back. Im at -2,2°...

    Rollbars for track - which options?

    Hey folks, as mentioned: Im looking for new rollbars. The car is tilting way too much with the OEM ones ( as you can see here https://i.imgur.com/H3hWHNA.jpg ) So what are the solutions? I found ultra racing but these are not adjustable. H&R got adjustables but only for ep3 - are dp3 / dc5...
