Stock rb25det neo questions

I mean it's probably likely that people overestimate their skills in dialling in a setup and noticing the changes.

I had SK shocks and springs, and added heavier springs and got them revalved by Sydney Shocks to suit based upon what I told them I wanted the car to handle like. I got back a completely different feeling set of shocks, which probably (?) feel great on track but holy hell are they rough on tram tracks and the like. The shock dyno actually looks pretty similar to Shockworks (from what I can surmise from a screenshot of a youtube video - and my dyno printout...)

Truth be told I doubt I'd be any faster or slower with either setup, or camber/castor combination. I also had whiteline eccentric castor bushes up front of my R34. I removed them and put in poly non-adjustable ones to soothe my OCD (nobody ever set the castor the same side to side, and it'd be near impossible to do) and be happy the wheel is centered in the well now for clearance reasons. Yes I wanted it to move 1mm 'back' :p

I've effectively set my castor back to stock, negating all the benefits of that which is supposedly massive. I've probably also altered toe and camber in a negative (detrimental) way. I can't tell any difference steering the car.

Sadly, it is a non-trivial exercise to set up to measure and correct bump steer. I am happy to show my rig, which involves nasty chunks of wood bolted to the hub, mirrors, lasers, graph paper targets and other horrors. Just in case anyone wants to see how it is done. I'll just have to set it up to take the photos.

I for one would love to see this. Save the HICAS locker and subframe inserts, I haven't done anything to the rear suspension. Factory camber adjustment is dialed all the way out though.

Jump on youtube, search for bump steer gauge and enjoy the show.

Yeah, my offer was more to show exactly how rough and ready the rig can be and still be useful. Youtube vids will definitely show cleaner setups. Same concept though.
