Multi purpose suspension setup, for track/drift (amateur) events

Start out soft, with low grip rear tires. You'll transition from one direction to the other slowly, and your speed will be lower. Increase rear grip, and your speed can increase. Increase spring rates, and you can transition quicker. You don't need a whole lot of changes to start drifting.

This ^^^^ is gold. Thank you!!! Made me realize that going too stiff is actually not a very good idea for a beginner. This has to be a part of every newbie drifting guide.

A good drift car would make for a good track car. I'd want a car that does not oversteer because you're going to create oversteer with the rear tires spinning. But the use of toe-out can help that initial turn-in to get things started. You want some balance.

When I tried wide front tires and skinny rear tires because my car was underpowered, I could slide it, but it was slow and transitions were difficult because the car was easy to spin. I'd want equal tire front and rear to start, and eventually wider rear tires when power level is increased.

What I did on my 240:
BNE Select top mounts, max caster and camber setting.
KL Racing controls arms.
BNE Quick Steer Roll Correctors, set to fastest setting and +4 Ackerman
250lb/in front springs, cut wagon springs in the rear
28mm bar in the front, 23mm out back (will probably take this off)
Welded diff.

Sounds good to me. Did the KL arms make the front track wider? What size wheel/tire and what offset? Everything clears at full lock, I assume? Mostly just curious, rather than asking for specific tips.

How's your power steering....which fluid, and did you need to add a cooler? I had to switch to synthetic when I went to the middle hole on the BNE roll center spacers, but I didn't need a cooler (autocross only).

Great insight into some actual setup figures. Thanks!!
What about the rear end stiffness (sway bars)? Same for both track/drift events?

The wheels are 16x7 oem steelies that I flipped the centers on. I can't remember what the offset it at the moment... but I can measure them in a few days.

The KL arms are 25mm wider per side, and move the ball-joint forward 15mm. I ended up plating the top and bottom after bending one at a drift day. There is light touching at full lock, may need rack limiters, or move to the middle setting.

PS definitely needs a cooler. It gets HOT and the pump sounds pissed when it's a hot day. I'm currently using Redline power steering fluid, and it seems much happier with that.

I want to remove the rear bar for more grip at drifting, it is pretty over-steer prone with the bar on the track as well.

Don't forget to look into rear subframe upgrades. You can reinforce the stock one or buy something from Ben.

I am aware of the trailing arms beefing up with weld on plates. Is there anything else? I'd appreciate a few search key word

I've seen Ben's name pop up in numerous threads, but was not able to pin point who is it exactly. Have a "link" to Ben?

bneshop.com is Ben. The rear subframe is a part that needs upgrading to put up with any abusive driving.

[mikep]

Yep.

That’s Ben.

Ahh, of course, Kaplhenke.
I've drooled over several items on that site...
