MysparkEV suspension mods

Well, the ’14 sparks are pretty soft, mostly in the rear suspension as the rear suspension is a swing axle with a 550 pound battery back there. I dropped it 1″ front by cutting the front springs and trimming the front bump stop 1″, the rear, I installed a 7″ 350lb rate spring from Summit Racing. These springs are shorter than the stock springs so I had to also install shorter shocks. Initially I used Bilstein sport shocks from a similar year Cruze but they turned out to be way too soft. I ended up using/modifying an adjustable Rancho shock. I have it set on setting #4 and it way stiff enough.

All these suspension mods eliminated the rear end squat when accelerating from a stop and stiffened up the ride- much more fun to drive now. In the traction department- the stock ECO tires are NOT made for grip. Cornering was ok but wheel spin was unavoidable when aggressively taking off from a stop. I changed the tires to Federal 595 rs-r tires- 195/50/15 front and  205/50/15 rear. They are the same diameter as the stock ones just slightly wider.

Results- Way better handling- like its on rails now- I have yet to hear it skid around any corner I have tried! The best part is no more spinning the tires from a stop. The 14′ 0-60 is around 7.8, which I could rarely get that fast on the stock tires. I can now get no worse than 7.5, had a best of 6.8- depends on the winds and road conditions. the ’15 says they are around 7.2 seconds to 60 but I find that hard to believe with the stock ECO tires- they do have a slightly lighter battery pack which anytime you take away weight from the rear in a FWD car, it will hook up better.

My biggest acceleration limitation now is the Torque management as its setup for the hard ECO tires. 0-30 is not impressive but after 30 is where it makes it up. I have clocked 30-50 in less than 1.5 seconds which is pretty fast- for example- I have a ICE car with a 270hp v6 that goes to 60 in 6.4 seconds BUT a normal 30-50 wot kickdown takes just under 3 seconds!

I am currently waiting for HP tuners to help me on the tuning- the reduction of Torque management to 30mph should help greatly as the electric motor in these sparks puts out 402 lb of torque from 0-2000rpm! This in a FWD= tire smoking, which is why Torque management is so important in a FWD (wrong wheel drive) car.

Ill keep this updated as progress is made!federal595rsr

The ’14 sparks have blue trim inside with no other options, never liked it, wrapped it all in carbon. Way better!sparkcarbon1

My 2014 Chevy Spark EV

sparkfrt1I’m posting my progress on my sparkEV, purchased it used in December of 2015. Dropped 1.5″, carbon wrap hood/door handles/plasti-dip wheels, grills and chrome trim.

Hello world!

I started driving a chevy spark EV back in December of 2015, as I can’t keep anything stock, I will post my progress and mods as I finish them.
