Bottoming out on corners
 

Sorry if this has been discussed. I searched but could find what I was looking for.

I just recently installed new wheels tires and coil overs. 18x9.5 +38 with 255/35 square. Fortune auto coils. When I’m going through corners at just a decent pace the tires are hitting the fender liners, mostly in the front. Today driving back home I went through a corner with a lot of bumps and the driver front hit hard enough to make the car try to turn to the left.

Damping is almost at full hard and fender height measures up to 24.5” fenders have also been rolled. Is there a way to make the car not bottom out on the fenders so hard besides raising it?

Raising it to be 25 1/2 inches to 26 inches is ideal to take hard turns allowing the suspensions and coil overs to travel properly. There shouldn’t be a problem with your wheels or your coil overs which leaves your height and alignment. I believe your too low. You either want to take the turns slower and “look” appealing to others or you can raise your car and take turns hard appealing to yourself and others with the handling of the car.

I was figuring that the only way to fix the problem would be to raise it. Now the next question is how high can the fortune auto coils go and still have good thread engagement between the coilover and the lower mount.

Also are you running the same wheel tire size? I do like the way your car sits.

Yeah, you need to raise it. You can probably do 25.25" minimum but I run 25 3/8" front about the same rear maybe 25.5".
Even at that height, I'll occasionally hear some rubbing driving Skyline

what are your spring rates and sway bars?

Everything kind of have to work together, ride height, spring rate, camber, coilover setting plus many more. You'll have to adjust them one at a time to get to you liking, will take some trial and error.

Start with the heights as mentioned, I'm sitting ~26" rear and ~25.25" front. Mild fender roll in the front, rear untouched. No rubbing unless I hit a big bump at high speed that cause a big drop, in that case I'll hear slight rubbing in the rear.

I’m not sure on spring rates but it’s whatever fortune auto does. I think 10k front and 8k rear. I haven’t gotten an alignment yet because i still wasn’t sure if that’s where I’m keeping the car which obviously it’s getting raised. As much as I like the fitment I love taking the car around the lake. But also looking at your guys setups I like how they sit. Once I get some time I’ll be lifting the car.
