I’m making this post because I see all kinds of fender flares on spyders but there just doesn’t seem to be much info or an organized place where everyone can show what flares they’ve put on their cars and how they did it.
I originally decided on the jdm fender flares because I saw a spyder with them and I always wanted wide wheels to further increase this cars already amazing handling.
The ones I chose are 3 inch fender flares as I wanted flares large enough to completely cover the oem fender curves. Cutting the oem curves out and attaching the flares above them means the 3 inch flares really only add 2 inches of width overall. The flares also are positioned pretty high so you will get about an inch of extra wheel gap so lowering the car aggressively is necessary.
I picked my wheels from my favorite choices on fitment industries because their site makes it easier to find the correct offset and they have plenty of options for wider wheels in the scarce 4x100 size.
I decided on a square setup, my wheel specs are 17x9 et 25 and I have a 15mm spacer in the rear since the front wheels would stick further out in a square setup. Honestly the 15mm spacer really isn’t enough and I may eventually go with a 1inch spacer in the rear (25mm) but I just ordered different flares and want to see how the fitment is for my new setup first.
The flares looked kind of wide so I went with a taller tire than I liked to fill the space plus I wasn’t sure how low I would be able to get the car as I was only running lowering springs. I chose 245 40 17 tires all the way around and the fitment looks good but in the future I will be ordering 245 35 17 tires to replace them.
After installing the wheels and flares using riv nuts to allow easy removal I knew I would need to lower the car more and did my research on cutting springs. Only certain springs can be cut and you have to have the correct type of strut with an indent for the spring to rest against. I also drilled a hole in the strut and used a metal zip tie to secure the spring in place so when the car is lifted the spring won’t get out of place since the spring is shorter. I had tein progressive lowering springs and they always felt way too soft and didn’t lower the car much.
I cut the stiff spring rate so the car still rides comfortably over bumps and I am very happy with how it turned out. I cut 2.5 coils off the spring half a coil at a time until I got the desired height which lowered the car about an additional 2.5-3 inches more than the teins and now there is virtually 0 body roll but enough suspension travel to make for predictable handling. Honestly the car rides and handles better than my sti with coilovers and custom spring rates. I would not recommend cutting linear spring rate springs very much, it dramatically stiffens the spring rate of the springs and without a progressive spring rate you will feel every bump in your head from hitting it on the roof so wear your seat belt if you do ; )
After lowering the car the tire would rub on the outside sidewall of the tire at full lock when turning the wheel so I had to take an angle grinder and cut out the entire pinch weld inside the fenders. Now I don’t have any issues but I definitely remember going through quite a lot of cutoff wheels for that, obviously everything I cut I painted so don’t worry it hasn’t rusted.
It has actually been a couple years since I installed the flares and I accidentally torqued down the bolts too tight and drilled the holes in the flares too big so they actually cracked where the bolts are touching them. I ordered a set of brz wide body flares made out of abs because I saw 2-3 spyders with them online and I am currently in the process of installing them. They just came in the mail today and I’ve got one front fender on already. They will take a good bit of time because there’s quite a bit of trimming you have to do to each flare plus measuring and repositioning 50 times. They do need to have some flex so it is vital to get the plastic fenders, the bolts flex and secure the fenders just fine. So far I had to bend the front tip of the front flare down in order to gain just a tiny bit of extra clearance for my wheels and also trimmed the inner fender lip.
