very good comment that maximum grip doesnt mean the car feels good to handle, even true in the context of motorsport. For my part I would like to say I'm pretty shocked at how overbearing the power steering feels on some modern cars. I feel nearly no difference in self-aligning torque between gripping on pavement and understeering in the slush in my current car.

Just dropping a line to say I really enjoyed this, and feel there’s a real lack of top-level, structured content in the car world. I for one want more lectures. Thank you! 😃

I bet this book will become one of the staples in car modifications for handling and will be used for decades. Wonderful work!

What an excellent bunch of videos you’ve been putting out. I have to say I’ve learned quite a bit and will have to get a couple of your books. Your video on intakes helped immensely in what I’m doing with my mk1 mx5. I’m adding a programable ecu which gets rid of the afm and goes to MAP. I went out and bought a mk2 1.8 air box that’ll fit perfectly. The intake to box is twice the size of the 1.6 air box and is on the other side away from the manifold. With some parts from Flyin Miata it should work perfectly. Handling and grip was also very interesting.

Great video! Im definitely going to need to buy the book! Ive been having some understeer when trying to accelerate out of certain turns and Im not even going high speeds(40ish) through a long curve turn. Im slightly cambered and have adjustable coilovers and after this video I believe I may have stiffened the front dampers too much. I also have to check on the tire tread.

Hey Julian! I am going to be buying your book soon but want to give a thank you for sharing your wisdom! Ive been focusing strictly on refining the suspension on my car. I took your advice and eliminated the rear roll since my car plowed alot. Completely changed the characteristics, so much more rotation. Cant wait to get the book and dig into it!

These are excellent points. 👍

Great info!

I full agree that lot of grip don't mean good handling, BUT (xD) I realize that good set of fresh tires makes a car controllable, predictable and progressive. I started my racing in grassroots events, where lot of people (included me) ride on really shitty, used tires, not bald, simply overaged. Car on this type tires was unpredictable on limit, and it no way to feel how much grip I have. When I put a set of fresh tires I'm shocked. Now tires communicate how much I can push, and even I push to hard, grip loss is not sudden. I learned this especially on motorcycle. Old tires, even when looks good are unpredictable on hard braking or in wet conditions, other hand fresh ones feels way more "rubbery" on handlebar. Now I may ride motorcycle on some level of slip and stil control the bike.

You hit the nail on the head on the progressive for me. My 02 wrx handles great and has insane grip on dry but the rest end likes to step out on wet. I’ve got swaybars in the front and rear, would the rear be too tight/stiff? Thank you
