Haha it seems like this was not the case! As I posted on your 1LE R Facebook post, the G3Rs keep proving to be as fast as slicks time and time again.

You're really buying more wheels still!!!!!!!!

Yeap I have seen this morning I remembered how much I loved this car.. exhaust sound is amazing and rev match does really help too

I went ahead and ordered Apex SM-10 wheels in 18x10.5" +22 fitment to be able to try 315/30/18 RRs in square size. They should arrive tomorrow. Hopefully, I can test them on the next club event scheduled on April 11th ..hoping that state ban till April 8th will be lifted by then

I'm still amazed you were able to get your 3/21 day in at ORP! Now, you continue to buy wheels and tires like women change their shoes... I'm super jealous!!

Do you think you are going to need any additional strut or knuckle grinding to make those fit?

It was a club event with about 8 participants but I really hope the next one isn't cancelled. I already sold my OEM wheels/tires as I won't need thrm much so currently have two sets 18" and 19". I will soon list the 18x10" front wheels for sale (as I received the 18x10.5" to be able to run 315s up front)

I am about to do some test fitment. I have more aggressive grinding than the last one so combined with that and the less degree of camber (used to be -3.0 on the old csr and -2.7 now) , I think it should be ok. Worst case, I will use 8mm spacer instead of 5mm. Will keep you posted

Interested to know the fitment. Side note, the 315 RRs aren't cost effective at all compared to the 295s. $130 a piece more!!

Yes,they're not like the 295s but still not too bad. I have listed my 295/30/18 (4 tires) Tires and Apex SM-10 wheels in 18x10" +25 sizes (pair /front) for sale in anyone interested

[glamcem]

On the other news. I received my new wheels (Apex SM-10 18x10.5" +22mm) to run 315/30/18 RRs. As I already had a spare set in 295/315-30-18, I decided to use the 315s out of that set and post the 18x10" wheels as well as the for 295 tires for sale.

I had them mounted and balanced at Chase Race and test fitted them after I came back home. Long story short, it's a tight fit but seems to be working . I am so glad that I let Doug to grind and weld the knuckles a bit further to gain some extra space. Combined with the -2.7 camber , it will work. For the reference, the chicken strips on the sidewall don't touch the knuckle and they're at least 5-6 mm long. I still keep my 3mm spacer and can combine with the existing 5mm spacer to make it 8mm (as I already have longer wheel studs) but it looks like it won't be necessary.



I also changed the differential after the first track day. It didn't seem that bad but I also couldn't really drive at last event that long too.

Also added the brake deflector and it looks huge compared to the OEM SS 1LE deflector. I am hoping that they also make a difference for cooling the rotors by looking at their size, I can guess they're very functional. I cannot believe this part is only $15, perfect fitment as expected from a GM OEM part and good quality

Nice! Hopefully you get to test them out sooner than later!

Whats the part number for brake deflector ?

[TheRealJA105]

So many 1LE guys are against the SS brake cooling deflectors, saying the 1LE doesn't need them. It may not need them, but why not add brake cooling? Especially for how cheap they are.

Thanks, I am hoping so too

Exactly. Without the Titanium shims and Castrol SRF on the previous car, I always felt that I could use more brake. So every little bit helps on this car, IMO. Titanium shims look like they made a noticeable improvement on keeping the temps in check. My temp sticker on the caliper used to read 430F ish and discoloration was pretty noticeable even after a short track use. With the titanium shims on the new car it didn't pass 330F this time. Of course it's still too early and on a hot day it may be different but from what I can tell they helped.

Castrol SRF also seems like a better brake fluid compared to Motul RBF600 , with its higher dry and wet boiling points.

I was considering to get some ZL1 brakes but I want to see if I can get away with these cooling upgrades. I really don't want to hassle, cost and additional weight if I can get away with these. Ryephile switched to ZL1 brakes at some point and mentioned that with the above mods (race pads, titanium shims, good brake fluid) OEM SS 1LE brakes would be fine and ZL1 brakes were a bit overkill. However, I have never had a brake system that I can say "overkill" so I am really curious to experience that

I can tell you running OE Ferodo HP1001/1 pads, StopTech 600 brake fluid and the SS Track brake cooling stuff (deflectors and rotor shields), I have been able to do lap-after-lap on all the tracks I've been to, for every single session. The only time I began to feel an issue was at Gingerman in late July when my front pads got down to around 5mm thick. Once I swapped a set of new OE front pads for the next day I was fine. Even Mid-Ohio in mid-August braking from 140-60mph for T4 I had no issues. I'm a big proponent of giving the SS Track stuff a go...

Speaking to Ryephile at Grattan when he tried the ZL1 brakes he mentioned that they seemed WAY over-kill without even track-dedicated pads (I think he started off running the stock HP1001/1 pads). It seems the SS 1LE brake setup is just perfect for the application (i.e. driving the car at or near it's limits, there is little margin in extra capacity, but it 100% works).
