Ikeya Formula Negative Front Adjustable Upper Arms For R33 Gtr

[CameronBNR32]

Hey all, just about to order front upper arms for the track car, but have found two different designs by Ikeya Formula.

Trying to figure out which type would be better for track use, the car is not registered and is a track only car, so as much adjustment into the negative would be desired.

Can purchase both designs but wondering which one to go for.... any info/advice?

Design 1

Design 2

thanks.

Design 1 is a bushed option better for street, it also allows you to stuff around with caster which is a bad thing.

Design 2 is a rose jointed and much stronger design, but it doesnt allow for as finite adjustments.

Just curious what the prices are for both?

Do you mean it isn't a bad thing being able to adjust castor? Or is it a bad thing because you shouldn't use the upper arms to adjust castor?

Sorry for the OT, but I just bought a similar set of the 1st design arms and it's getting aligned tomorrow
