Stiffer springs at dnc? Was it high grip? Generally stiffer springs make the car worse in bumps unless the goal is to skip across the top of the bumps. That is Mugen setup territory there.

at the start some used stiffer springs, which is needed if you lay down the shocks, then migrated back to blue and I think I saw orange on some as the track blew out. Not sure the grip, looked groove on the race line, but imo 28 secs on a big track is quick.
I do like the concept of skipping or moreover getting the frequency right particularly in rebound. Lots of cars bounce around the track because there’s no oil in their shocks because they think the tire needs to travel down every rut to maintain traction. Maybe, but what goes down must come up and usually it’s with interest. Everything is a compromise but I like the idea the sprung weight on a car shouldn’t move when hitting a bump only the suspension. Mugen/ Maifield did well. Maybe they’re on to something. The MP10 does appear to have adopted a few Mugen concepts.

remember that the mugen has been develop towards bumpy tracks so they had an adavantage and the mp10 was develop more toward smoother higher grip tracks and you can really see that on the geometry.

just a quick and simple question. Is it worth it to upgrade to the mp10 if I have the tki4 anniversary edition?

Do you have a setup sheet from DNC ?

if you’re racing on tarmac maybe .... anything less and I reckon it’ll push like a pig.
