There are a couple others who have done it, but not many who have actually weighed their car and none with the same sort of mods I'm doing. There's going to be so much changing on this car in the first build that I'm ballparking the theory. I fully expect to change the balance of things down the road after I've driven the car in some track days and have a good idea of how it actually handles with the changes.pmbrunelle wrote: ↑Wed Feb 09, 2022 10:28 pm Since you're moving forward with wheel/tire/suspension parts selection, do you have an idea of what your weight distribution will be like, even though your engine isn't installed yet?
There are some other K-powered Fieros out there, so maybe those folks can tell you their weight distribution.
That said, the K20A2 swap with a relatively light flywheel, deleted P/S pump, and lightweight exhaust *should* drop 50-100lbs off the back of the car compared to the stock Duke with the 5 speed. I'll also be moving the battery to the front at the same time. My interior lightweighting will basically just be breaking even on weight with the roll cage going in, and that's all centralized in the car so shouldn't affect the weight distribution much. My wheels are pretty light (~17lbs front and ~18lbs rear), but the tires will be heavier than stock. Brakes will be 2 piece rotors so not a ton heavier than stock despite being much larger, and the calipers will be light Brembos which will probably be similar if not slightly lighter to the stock 88s. The suspension should shave a bit of weight off with tubular arms and links but not a huge amount. I have removed the spare tire, jack, and associated brackets from the front, but I'm also adding A/C components in which my car didn't come with (functional A/C is a requirement for me for summer track days).
My car is an 88 base model which supposedly is around 45% front and 2600lbs in stock form (I'll try to get it on a set of scales before yanking the motor to confirm), I'm expecting after all the modification it will break even on pretty much everything except the engine swap, so should come out slightly lighter than stock, in the 25xx range without driver. The weight reduction off the back and moving the battery to the front should put me around 47-48% front.
My tire choice is limited partly by what sizes are actually available in the compound I want to run, so I'm going with a 255/275 stagger (48% front) to start with. I would ideally do a 245/275 but 245s aren't available at the moment.
). The only ask I've had was from the couple with the new volvo next to me, that I put a blanket over their car if I'm sanding on that side to keep the dust off
