Just a quick review on my installation - 2018 BRZ tS
Just finished up the Flex Fuel installation on top of the Harrop install today. I am surprised how smooth running the car is on E85. it smoothed out with the SC installation a bit, with the Flex Fuel it runs very smooth. Most notably these two installations have effectively lowered the time/mileage interval on tire rotation! Driving this car on E85 certainly brings new meaning to the expression “driving under the influence of alcohol”. There might be a form of alcohol addiction in the future - though not the type you drink. Neal at the The Racer's Line has done installs on both the Edelbrock and the Harrop. He says the Edelbrock is about 60# additional and the Harrop about 40#. He says that when lowering the intake/blower assembly onto the engine the Edelbrock requires two people, the Harrop he does by himself. If there is a change in how the car sits with the SC installed it is not that noticeable, maybe no more than 5 mm. The installation of the SC does change the dynamics of the handling. You can detect the weight increase. The tS is a bit of a firmer ride to begin with, the ride in the front with the SC installation is definitely firmer. Changing driving technique slightly easily works around most of the issue. The increase in power/torque and generally the character of the car from the installation of the SC is definitely worth it, in spite of some the shortcomings. The E85 puts it over the top, even on my car with the 95 mm pulley and stock exhaust. For people that don't want to put the kind of jack that it takes for a FI installation, and/or don't want the weight increase, IMHO, I would say that there would be notable gains from just going with E85 and a proper tune. Of course any E85 project is based solely on availability. I was just lucky to find that there is a station in close proximity to where I live. I will be working on weight reduction later. |

Would you all suggest other suspension upgrades for the extra power and weight? Like it was suggested to increase the front stiffness of the springs/coilovers, but what about doing a bigger sway bar. I have been considering that because the rear is unruly now, even with 265's in the rear on sticky tires.

For me, I will work on weight reduction before I go with suspension mods. I have a tS, so the suspension is already firmer. One can get addicted to pouring money into this car, but to what end? Is the incremental improvements worth the cost? Would major suspension mods give you what you need? Will you have more fun working on the car, or driving it? I have to remember that as much money I throw at this car, it's not going to ever be a McLaren. All this is just food for thought. After all, "YMMV"! |

I think in the long run I want to upgrade my lowering springs to coilovers and also do a front sway bar. Going lighter would be nice, but I don’t want faster revving mods at this time like LEFW or LWDS. The best thing I can do to remove weight off the front is removing the injector covers, going with headers, AC delete, crash beam removal, windshield washer fluid delete, etc, but none of that is an option right now.

Ideally I would like magnetic suspension where I could run it soft on the street and flip a button to have it tighten up for canyons and track days. The other ideal would be to have a traction control and VSC settings that are adjustable, instead of just on and off. Even with 265's and sticky tires, I am losing traction with aggressive driving. The traction control light is getting annoying, but I'm not about to remove all the nannies for my aggressive street driving. If a sway bar helps with control then it would be a cheap, at minimal, temporary solution.

I'm sure coilovers are lighter than springs and struts, but I could be wrong. When I get them, unless I find a sweet deal on a used set, I'll probably drop some coin and get something decent like I mentioned above. No point in getting some $750 coilovers for just a 1'' drop and expect them to perform better than stock.

Making it stiffer will just make it even harder to put power down though. IMO if you're struggling to put power down now, keep it soft and keep the traction brackets, get stickier tires. |

I'll probably just alter the driving style for a while and see what I can do. I'll consider those MCA mounts, but I'll probably wait for when I do coilovers then see if it needs more like a sway bar up front.
